You obviously have a lot of information about this individual; wha tyou need to do is narrow your focus for a moment and tell us what it is you might possibly be hoping to find about him.
Right now, as I have understood (or misunderstood) it, the logic of your statement goes something like:
"Tell me any detail or fact about this person, even though I have all the vital details and facts about the births and deaths of all family members close to him."
This is a very tall request, with no focus.Give us something more concrete.
Example:Such and such a person had a friend from a certain neighborhood of Chicago and they were in the clothing business together; how can I find ...... about this business relationship? Would business licenses have been required in 1922?
