Dear Flakdodger
Sorry this is such an old link but I have just found it. The photograph you showed appeared in Your Family Tree magazine a few years ago and I was able to obtain a larger detailed picture to analyze. In front of the seated people are a number of gravestones which I was able to manipulate using photoshop to help identify them. One of the gravestones is to Henry John Sykes aged 3 who died in 1830, son of Samuel and Sophia Sykes. The only one I can find who matches this description was born in London in 1826 around St Mary-le-Bow. so perhaps it is not Leeds but London. I am attaching the photo. What do you think?
