More stuff and frustration

Well i didn't think i could get any further with Harry but i did a bit more digging and managed to find more. It seems i have stumbled across his first marriage.
He married a Beatrice Ibbotson in 1927 at the age of 25(they both were). However, the marriage didn't last long and she died some 4 yrs later at 29yrs old. Now forgive me for being suspicious but doesn't it seem a bit odd that he had 2 wifes and both died at very young ages? I have ordered their marriage certificate and Beatrices death certificate to investigate further. I'll have a reputation as the next Miss Marple at this rate!
So last night i decided to switch tactics and look at dads side of the family. I know his mum and dads name and have his mums birth certificate so tracing her family is a bit easier than his Dads. His mum Clara Wild was born on 3rd December 1898 to Joseph and Clara Wild nee Jackson. At the time of her birth she had a sister, Doreen, who was 2 yrs older. They lived at 9 Court, 5 House, Bernard Street, Sheffield. Joseph was an Edge Tool Grinder. However, finding James barker is more difficult. First port of call i thought would be a marriage registry but one doesn't seem to exist and i'm a bit stumped now. I'm going to get in touch with the local registry office and see if they can help as i'm sure they must have been married in Sheffield. Now Dad was one of 16 children, yes 16!!!! I've done a search and can find 14 registrys but am struggling with a couple so i'll let you know how they go.
So here are a list of the ones i have found so far. It seems Grandma was having a baby every yr for a lot of her life!
