It makes more sense that Percival Powning Trestrail's grandfather was William and his grandmother Eliza Powning.
But I wonder if my grandfather's parents (?) died and he went to stay with his grandfather, William Trestrail, who was widowed from Eliza, when my grandfather, Percival, was 15.
I am going to state that this is absolutely my grandfather's grandparents.
he only bmds for a Percy Trestrail on the GRO index in Cornwall are the birth reg in march qtr 1886 and the marriage in 1923. There is no Percival showing up in bmds or on the census. The Percy that I posted is the only one who appears.
Percival Powning Trestrail was at sea at age 7. That would be 1892. He was at sea for many years, and it looks like 8 years later he was back in Hayle at age 15 living with his grandfather, William, who was then widowed from Eliza.
The marriage is indexed as
Percy P Trestrail march qtr 1923 Redruth vol 5c pg 319 to Bessie Knight
This marriage reg for the grandparents looks to explain Percy's middle name - Powning
William Trestrail dec qtr 1843 Redruth vol 9 pg 299 with Eliza Powning on the same page
Possible for Eliza's baptism?
