Never worked out why he used the name Mitchell. I assumed because of the case and because they were breaking the law, it was just a fake name used. The marriage in 1933 was nullified. Basically they lied on everything!
He is Horn on everything else. I am a Horn, so is my father, my Grandfather and when they 'remarried' properly, they use Horn and all other information on that certificate adds up.
Thank you so much avm228 for finding that information! None of those names ring a bell and I haven't seen them pop up anywhere before. I wonder how long they were there for or, if Violet was also lodging from them, if they had previously had other boarders.
I attempted to go down the route of him being adopted and/or whether George had been put into a home. Honestly, I didn't know quite know where to look, but wherever I tried, nothing showed up.
I've also tried checking all relatives on the 1911 census and didn't find George staying with any of them.
I'll try checking the address a few years later.
