John and Mary Sullivan Milwaukee st Oconomowoc
Looking for information on the John and Mary (Collins) Sullivan family who lived in Oconomowoc at least in 1900 and 1910.In the 1900 cencus it lists children: Ellen (who was a teacher in 1910), Mary (or Margaret), George (could have been a knickname for John), Bertie(?) a son and Margie. George/John and Bertie might have died between 1900 and 1910.
ANY info on this family would greatly be appreciated.
