The location in Queens is the Long Island City area. The time frame would be from around 1870 to 1970. The following surnames could be related through marriage. Bischoff, Schmidt & Zehner. I am leaving the message as brosd as possible in case decendants do not recognize first names but will recognize the last names. I have tried more detailed mesages in the past with no effect. This one may be more of an eye catcher. Worth a shot.
