Hi John,
I'll take a look at all the info from the SSDI and see if I can connect it up to our William and Alexander Kruk.
I shall have to try looking for any obituries as this might throw some light on possible offspring.
The 1938 Newark Directory shows Stella Kruk, Widow, Joseph Kruk who was her late husband's brother, William S. Kruk, and Helen B. Kruk. I assumed Helen was Stella's daughter but from what Shelley has posted, she could be Joseph's wife, (except the Portsmouth Directory says widow of Alexander - very confusing). I assume that Alexander had left home by then, possibly got married while William was still at home unmarried.
There is also a Thomas Kruk (wife Sophie) at this address - no idea who these people could be.
Richard.
