Hi Jan
Well, I thought I had some crackers but this one takes the biscuit.
I can't imagine what was going on with the 1911 census, perhaps he misunderstood what he was supposed to write.
I couldn't see a birth for a George J Bartram either.
So who knows.
I think you have the correct birth for Emily 1862 in Shoreditch, at least she is constant with a birth date, but where is she in the census. I don't think she is the Emily who married James Thompson in 1887, I've been trying to find this couple but I'm not sure that I have so I'll keep checking but one thing that I'm wondering about, there are usually 2 couples on the marriage reference page so did Emily Back actually marry James Thompson or are there a bride & groom missing, it's just a thought.
Could this be your James & Emily's marriage or did they just not bother, don't suppose they could have married abroad.
I did spot a James Bartram born London City in c1850 on the 1871 census, he is in Wales, a private in the 13th Foot but I think his parents were Thomas & Abigail Bartram. There has to be something wrong with the name Bartram or Hackney/Shoreditch as there is no birth showing for James so, could he have been born something other than a Bartram & his mother then married a Bartram or born a Bartram but on the census under a step fathers name.
Oh what fun
As you say, he must be there somewhere it's just "looking outside the box".
I'll keep at it with fingers crossed, maybe they will both jump out all of a sudden.
