I found on the internet that Robert H. Jacobus (the 3rd) sold a home on 42 Plymouth St. in Fairfield, New Jersey for $125,000 to a Michael Hammer.

A Robert Henry (Bob) Jacobus lived at that address. Bob's sister Ruth Louise Jacobus (married name Dingler) was my Grandmother.

Any information would be helpful!!

Sincerely,
Karen L. Both
