Hi Heather
Thanks for the information. I think you have hit the nail on the head!
I have actually applied for this birth certificate last week from Llangefni Register Office and waiting for it to arrive.
I have received the marriage certificate of Owen Hughes Jones marrying a Mary Griffith in 1877 and it has Glan Morfa, Pentraeth on it. This information fits in with my family as well as the information you have given me.
To explain, Mary Griffith lived at Tyddyn Glan y Mor/Glan Morfa from an early age, she is shown in the census 1861-1881 as a niece of a Griffith & Ann Williams. In the 1881 census she is shown as Mary Hughes (married) with a daughter Ann Jones-Hughes (suspect this may be the wrong way round). The Griffith part may be down to welsh patronymics and that she changed it to Williams on official registers?
The confusing thing over the years is on Mary Griffith's marriage certificate her father is shown as John Griffith, Pen y Traeth, Pentraeth which is what we as a family always thought.
On Ann Hughes' is marriage certificate she is shown as living at Tyddyn Glan y Mor and her father is Owen Hughes, the Jones has disappeared.
On Owen Hughes-Jones' marriage certificate his abode is Carreg Landeg, Pentraeth and his father is David Jones.
I think you have solved part of the question but so many more have opened up....Why change from Griffith to Williams, why drop the Jones and where does the Hughes come from?
Diolch
