How to Trace Welsh Family Crests Using National Library Resources

A Welsh coat of arms rarely travels with a surname. It travels with a bloodline, and that line generally has to be proved, generation by generation, before anyone accepts it. That is why the National Library of Wales in Aberystwyth is where most searches begin. Its manuscripts, deeds, wills and pedigrees survive in unusual depth, and a growing share is described — sometimes digitised — in catalogues you can search from home. What follows is a practical route through those collections, the order to tackle them in, and the point at which a specialist should take over.

What Welsh heraldry actually records

Start with a piece of vocabulary that saves a great deal of confusion. The crest is the figure sitting on top of the helmet: a lion, a wyvern, a plume of feathers. The coat of arms is the whole design on the shield, and it belongs to a particular person and their descendants — not to everyone who happens to share their surname.

In Wales that distinction matters more than almost anywhere else, because surnames arrived late and kept moving. A man in sixteenth-century Carmarthenshire might be recorded as Rhys ap Dafydd ap Ieuan, while his sons took different surnames again, sometimes from the father's given name, sometimes from a place. Welsh heraldry also follows its own logic. Many arms in the Principality are claimed from descent out of the old royal houses — Gwynedd, Powys, Deheubarth — and cadet branches differenced the shield or quartered new arms in as heiresses married into the line. So the real question is never "what are the arms of my surname?" It is "which line do I descend from, and what did that line bear?"

Begin with the National Library's online catalogues

Everything starts at Llyfrgell Genedlaethol Cymru, the National Library of Wales. Its catalogue covers printed books, manuscripts, archives and pictures, and a separate archives and manuscripts search is where deeds, pedigrees and family papers are described. Several related resources are free and searchable from anywhere:

• Dictionary of Welsh Biography — short lives of Welsh men and women, frequently noting arms, houses and descent.
• Welsh Newspapers Online — Welsh newspaper pages from 1804 to 1919, useful for funeral reports, estate sales and memorial notices that mention hatchments or arms.
• Welsh Journals Online — includes the National Library of Wales Journal and the Cymmrodorion transactions, where antiquaries published pedigrees, church inscriptions and corrections to earlier work.
• The Library's own catalogues — search the parish, the house and the family name together, because cataloguers often filed material under the estate rather than the surname.

Search tactics matter. Welsh surnames mutate in the records: Llewellyn and Llewelyn, Vaughan and Vychan, Pugh and ap Hugh. Try wildcards, and try the parish name on its own. A search for the parish plus the word "pedigree" or "arms" will often surface a manuscript nobody has looked at for a century.

Manuscripts where pedigrees and arms survive

The Library's manuscript collections are the core of Welsh genealogical research, and several are unusually rich in heraldry: Peniarth, Mostyn, Llanstephan, Cwrtmawr and Brogyntyn among them. They contain armorials, that is, collections of painted or blazoned shields, as well as pedigree rolls and the notebooks of heralds, genealogists and country gentry.

Three named sources are worth knowing before you order anything. Lewys Dwnn's heraldic visitations of Wales and the Marches, printed by the Welsh Manuscripts Society in the nineteenth century, record the pedigrees and arms that families claimed in the sixteenth and early seventeenth centuries. Llyfr Baglan, a heraldic and genealogical compilation associated with Glamorgan, was edited and published in the early twentieth century and is a standard quarry for south Wales families. And Peter Bartrum's Welsh Genealogies, covering the medieval and later periods, remain the reference point for early descent; they are available to consult in the Library's reading rooms and in many reference libraries. Armorials usually describe shields in Latin or English blazon rather than in pictures, so a little vocabulary goes a long way.

Wills, deeds and estate papers: proving a line

A pedigree convinces nobody on its own. You need documents that name relationships. Before 1858, Welsh probate was handled largely by the diocesan consistory courts of Bangor, St Asaph, St Davids and Llandaff, together with the Court of Great Sessions, and the Library holds a substantial share of the surviving wills, inventories and administrations. From 1858 onwards, look to the Principal Probate Registry and its district registries. Wills are gold dust because they name children, spouses and sometimes the house itself.

Deeds do the same work for land. Great estate collections such as Wynnstay, Mostyn, Crosswood and Penrice and Margam contain thousands of title deeds, settlements and family papers, and their catalogues are searchable by place and person. Work through them steadily: find your ancestor as a party to a deed, note the property, then look for the next generation in the same bundle. The trail usually runs through the land rather than through the name.

Monuments, maps and local collections

Parish churches are the most underused heraldic archive in Wales. Wall tablets, floor slabs, stained glass and funeral hatchments frequently carry arms, and the same arms may appear on a tomb in a churchyard. The Royal Commission on the Ancient and Historical Monuments of Wales records many of these monuments in its online database, Coflein, which is searchable by parish and by site.

Tithe maps and apportionments of the 1830s and 1840s are another practical tool: they name owners and occupiers plot by plot, and the Library has digitised large numbers for Wales. If your family held land, the tithe will place them precisely. Beyond the Library, county record offices hold parish registers, poor law records and solicitors' collections, and the Archives Wales portal lets you search across many Welsh archive services at once. Local antiquarian journals and transactions often contain articles on a single house and its families, complete with a description of the arms.

Reading what you find, and knowing when to stop

Blazon has its own shorthand. Or is gold, argent silver, gules red, azure blue, sable black and vert green. A lion rampant is rearing; passant is walking. Counterchanged means the colours swap between quarters. If a shield carries several quarters, that is a gift: each quarter usually represents a family brought in by a marriage, and each is a line you can research separately.

Two cautions. Visitation pedigrees were sometimes accepted on the word of the family concerned, so treat them as leads to be tested rather than as proof. And arms are granted to individuals, not to surnames: a "family crest" bought against a name is decorative, not evidence of anything. The College of Arms in London has jurisdiction in England, Wales and Northern Ireland — Scotland belongs to the Court of the Lord Lyon — and it holds grants, visitations and indexes. It will search its records for a fee, and it is the body that settles a formal claim to arms.

Practical next steps

1. Gather what the family already has: seals, rings, silver, bookplates, gravestone photographs, funeral cards, a family bible. These often name a house or a parish.
2. Search the free resources first — the Dictionary of Welsh Biography, Welsh Newspapers Online and Welsh Journals Online — for the surname, the parish and the house.
3. Search the Library's archives and manuscripts catalogue, note the reference numbers, and check whether a digital copy exists before ordering.
4. Order wills and deeds and build your line one generation at a time, recording parishes as you go. Print, or photograph, everything you find.
5. Check church monuments and tithe maps to put the family on the ground, then try the relevant county record office.
6. Email the Library's enquiry service with a specific question: names, places, dates and what you have already checked. Staff are generous with their knowledge when the question is precise.

Allow weeks rather than days for documents stored offsite, and keep a research log with every reference number and date. A reader's ticket is straightforward to obtain, and much of the work can be prepared from home before you travel to Aberystwyth. If you are working towards a formal grant or confirmation of arms, take professional genealogical and heraldic advice early — it will save you from building an elegant edifice on somebody else's ancestor.
