Thanks William,
I can eliminate the marriage to Owen Hughes in 1877 - the bride's father was Henry Parry and the bride was 24 at the time. Also their place of residence (both at Bridge Street, Llangefni) and the place of marriage (Bethesda Chapel, Amlwch), while not impossible, seem unlikely. 'My' Elizabeth Parry was the daughter of David Parry and would have been 30 in July 1877.
I've searched through the records of Anglesey marriages and cannot find a possible candidate for 'my' Elizabeth Parry and husband surname Hughes, so I think they married elsewhere. Neither can I find a census record for her, as either Parry or Hughes, between 1871 and 1901 (I have RG9/4372/39/31 as a possible in 1861).
I previously assumed that the middle name Tyran came with marriage but perhaps it was adopted by Elizabeth Parry/Hughes as a middle name because it had some family significance. I have found a few other instances of Tyran (or variants) in the Llanfair-yn-Neubwll records:
Death 6 Mar 1844, Tynddol, Llanfair-yn-Neubwll – Sarah Tyran, 89, widow of Henry Tyran (labourer). (Holyhead 2, 30, 150).
1841 census (HO 107/1358/13/8) - Tynddol, Llanfair-yn-Neubwll – Sarah David, widow, pauper, 80.
Marriage 24 Jan 1785, Henry Tyrer & Sarah Davis, Llanfair-yn-Neubwll (IGI M09002-1).
Baptism 30 Oct 1785, David Henry, parents Henry Tyrer/Sarah, Llanfair-yn-Neubwll (IGI C09002-1).
David Parry, Elizabeth Parry’s father, is my great(x2) grandfather, and is a major ‘brick wall’ in my family research. I can speculate that he is a child of Henry Tyran/Tyrer but his age at censuses and at his death show that he was probably born 1792/3 and is not the David Henry baptized in 1785 (above). I cannot find any evidence for other, later children of Henry Tyran and Sarah.
Any suggestions?
