Thanks for your reply. John Gange was my Great Grandfather, so I want to follow my family name. My Grandfather, John Wilfred Gange, remained in Bristol, while Mary Ann Gange (Taylor) and his siblings went to Winnipeg between 1908 and 1913. John Gange was admitted to Bristol Lunatic Asylum in 1911 and died there in 1913. I have various certificates, shipping records, etc if you are interested.
Please get in touch if you want any information about my branch of the family.
