Hello Gilbert! How lovely to welcome a new Family Member! I believe we are 2nd Cousins once removed as my GGrandmother, Florence was William Percsys Sister.
I do know quite a bit about the Family as I've been researching our Tree for about 3 Years.
William Percy (known as Percy?) was born in 1882 and Baptised 12/03/1882 when their address was 4 Beswick Rd, Walthamstow . I think you've been told Cornwall rather than Cornhill?
There were 4 Children - my GGrandmother, Florence was the eldest born 1881 and 2 younger Siblings, Walter born 1884, and Theresa born 1886.
I have them on the 1891 Census living at Elmsdale Rd, Walthamstow and on the 1901 at 3 The Pavement, George Lane, Woodford where their Mother, Mary Jane was working as The Manageress of a Cigar Business which I believe was owned by Wiliams Brother, John Alexander.
I think William/Percy emigrated to Vancouver c1911, initially on his own. I don't know what made him go to Canada?
I have Grahame born 1909 in Scotland and your Dad, Gilbert born 1912 in Vancouver? Did Grahame have Children?
I have found some records of their life in Canada using my Ancestry subscription.
My Mum, Doreen (Florence's Grandaughter) was born in 1929 so is 85 now (with memory problems) so never met William - but it was her that told me about Williams emigration and his 2 Boys, Gilbert and Grahame.
Via this Site I found another relative, Nigel Rixon, who is Theresa's GGrandson. I shall email him and tell him about you! My email address is
*There's probably a lot more information that we can swap.
I've added you to the Family Tree now

Happy New Year!
