I'll give you what information I have with regards to my dad as I knew him Hugh Albert Mclennan Kenny to give him his full title, my maiden name was Patricia Ann Kenny. My dad was born on 23/03 1910 and registered as Hugh Albert McLennan in Queen Charlotte Hospital in London. His mother's address on the certificate is 14 Harcourt Street St. Marylebone at tha t point my gran was listed as single. In the 1911 census my father is still McLennan but lives in the household of Leonard Jacques. he 1 year old and listed as son of the family. Also in 1911 Annie must have met Francis Kenny and Married him on the 8/03/1911 he is 50 and a widower and she is 37, the addresses for both of them is 14 Harcourt Street St Marylebone, I have a copy of the marriage gertificate, later year Lilian Elizabeth Kenny is borh, my dad's half sister. sometome between then and when my dad was a young boy they came back up to Scotland without Francis and by then my father is known as Hugh Albert Mclennan Kenny. when Annie died in 1935 her address was duncanston, logie wester and it was registered by lilian and her addres was Mulchaich Conon Bridge. my father was in the army for years, surely there must have been some sort of a record of the name change. I tried to get a copy of my fathers army records but they can't find them so i'm completely at a loss now I don't know what to try next. HELP.
