In Finding birth/baptism/marriage record for Priscilla who married printer Henry Hughes probably about 1810 in Breconshire, Wales? I sought vital records for Priscilla Hughes, the printer, of Struet, Brecon, Wales.
I now suspect that Priscilla may have been Priscilla Thomas who was baptised on 11 May 1782 at Hay, Breconshire, Wales, to Thomas Howels and Susanna. This is based on her age of death being 57 in 1839, the county where she seems to have spent her known life being Breconshire (Brecon, Hay and Talgarth), and her relatively uncommon Christian name.
"Wales Births and Baptisms, 1541-1907," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:FMMS-KWL : accessed 23 August 2015), Pricilla Thomas, 11 May 1782; citing HAY,BRECON,WALES, reference ; FHL microfilm 104,467.
I have not seen an image of this baptism and am wondering how to interpret her surname? I am assuming that she was "Priscilla daughter of Thomas [Howels]" so would it be appropriate to record her as Priscilla Howels?
