Hi Robert,
I know this is an old thread but I am also trying to find out details Re: Jelley. I wonder if we are related (See below)
Jeanette (myself) 1958
Barbara Jelley 1935 (My Mum)
Walter Thomas Jelley 1909 My Grandad
Arthur Thomas William Jelley 1878
Albert John Jelley 1854
Thomas Jelley 1821
James Jelley 1782
John Jelley 1755
All from the Dorking/Wandsworth area.

Walter Thomas Jelley changed his name by Deed Poll to Avery (My Mum was in school when this happened). He hated his Father so much he took his Mother Rosina's maiden name of Avery as his new surname. (Walter's Brother Francis did the same and became Angliss, his wife's maiden name) I have always been fascinated by Rosina Avery, yet have come to a dead end with her. She placed her 3 Sons (Arthur 1903 Francis 1906 & Walter 1909), in a workhouse in St Olav and left with 2 of her youngest children Richard (Born 1913 & Who I know nothing about) and also Rosina Junior 1911 who I believe died from TB before the age of 1 year (1912). Would love to hear from you if our tree overlaps, and any information you might have.
I live in Sydney Australia
Regards
Jeanette
