I think this is Henry, adding on from William's great find! The name of mother on marriage is wrong - but correct on death record?

Sadly looks like Henry left no descendants. The spotlight for the DNA connection returns to John R perhaps.
Just to mention, over years I have come across quite a number of people - especially males - who sprout a middle initial after immigrating to America, when they never had a middle name prior.
