Welsh Translation Services

Prism Language Solutions translates Welsh into English for USCIS filings, courts, credential evaluators and family researchers, and English into Welsh for organizations that need a Welsh version. Welsh is an unusual entry on a translation list because the demand is modest and honest about itself: nearly every Welsh speaker also speaks English, so almost all of this work is documents rather than interpreting. Certification is by signed Certificate of Translation Accuracy.

The 2021 census recorded 538,300 people in Wales able to speak Welsh, 17.8 percent of the population, and the American Community Survey for 2017 to 2021 put Welsh home speakers in the United States at roughly two thousand. The language has official status in Wales under the Welsh Language (Wales) Measure 2011, which also created the office of the Welsh Language Commissioner and the standards regime that public bodies work to.

Bilingual Welsh Certificates That Still Need a Translation

Births and deaths in Wales can be registered in Welsh alongside English, on forms prescribed in both languages by regulations made in 1987. The printed headings on such a certificate appear in both languages, which is what misleads people. The entries made by the registrar do not: where the registration was taken in Welsh, the occupation, the place of birth and the informant’s details are Welsh words sitting inside English-looking boxes.

Every non-English word has to be rendered for USCIS, so those entries need translating and certifying even though the document is half in English already. It is a short job and an inexpensive one. The alternative, filing it untranslated and hoping, is how a straightforward petition collects a Request for Evidence. See certified translation and birth certificate translation.

Welsh Chapel, School and Legal Record Translation

The other half of the work is older and more interesting. Nineteenth-century Welsh nonconformity ran in Welsh, so chapel membership rolls, baptism and burial registers, minute books and memorial inscriptions are frequently Welsh-only, and they are often the only surviving record of a family that emigrated to the Pennsylvania coalfields or the Ohio slate country. Welsh-medium school reports and degree transcripts come in for credential evaluation. Wills, tenancy agreements and contracts drafted in Welsh turn up in probate and in litigation.

Handwritten chapel material is the slowest of these and the most rewarding to get right. Our version gives what is on the page, marks what cannot be read rather than guessing at it, and keeps the Welsh form of a name or a farm beside the English so a researcher can carry on searching.

• Bilingual birth, marriage and death certificates with Welsh entries
• Chapel registers, membership rolls and minute books in Welsh
• Welsh-medium school reports and transcripts for credential evaluation
• Wills, leases and contracts drafted in Welsh, for probate and litigation
• Memorial inscriptions, family letters and diaries

Welsh Place Names and Surnames on a Certified Document

Two habits of Welsh records cause most of the confusion in a file. The first is the place name with two forms: Caerdydd and Cardiff, Abertawe and Swansea, Casnewydd and Newport, and a great many smaller places whose Welsh and English names look nothing alike. One certificate uses one form and the next uses the other, and a reader who does not know assumes two different towns. We give both forms wherever a place appears.

The second is the surname pool. Welsh surnames derive largely from patronymics, so Jones, Williams, Davies, Evans and Thomas cover an enormous share of the population, and a parish in 1861 can hold a dozen men of the same full name. Older records also carry the patronymic construction itself, with ap or ab meaning son of, which is how Ap Hywel became Powell. We translate what is written, explain the construction in a note, and leave the identification to the researcher or the attorney.

English to Welsh Translation for Organizations and Families

Translation into Welsh is a smaller stream and the reasons for it are usually not practical necessity. A family wants a memorial inscription, an order of service or a wedding reading in Welsh. An organization with a Welsh connection wants a bilingual page or a certificate. Occasionally a US body corresponding with a Welsh public authority wants its side of the exchange in Welsh as a courtesy, since Welsh public bodies operate under language standards at home.

We assign a native Welsh translator and we ask about register and dialect before starting, because the northern and southern varieties differ in everyday vocabulary and a text pitched wrongly reads oddly to the family it was made for. For anything ceremonial, tell us how it will be read aloud.

Welsh Interpreters, UK Apostille and Translation Cost

Requests for a Welsh interpreter are rare and specific, and we would rather say so than sell one. They arise when a speaker chooses to give evidence in Welsh, when a Welsh-language document has to be read onto the record at a deposition, or when an elderly Welsh speaker’s English has receded with dementia and only the first language is left. No state certifies court interpreters in Welsh, so a court works from a qualified one, and video is normally the practical route. See court interpreting and, for the same pattern in a related language, Irish.

Documents from Wales are UK public documents, and the United Kingdom has been in the Apostille Convention since 24 January 1965, with the apostille issued by the Foreign, Commonwealth and Development Office rather than by any Welsh body. Have it attached before translation so the stamp is covered in the same pass; see apostille translation. A short certificate with a few Welsh entries is quoted from around $24.95 as a US market guide and usually returned within a business day; handwritten chapel material is quoted individually. Ranges are on the pricing page.
