Your Mathias was the son of John Kartes and Elizabeth Weber. I recall that this Mathias married 'Wally'. I believe Matt died in Waconia, Carver Co. MN. Waconia is perhaps 10-12 miles from Chaska, where the family of John and Elizabeth resided since c 1881. I have a copy of his obituary on file. Do you need a copy?
John may have had a brother named Peter living in Oak Creek township, Milwaukee Co. Wisc. John and Elizabeth were married in Oak Creek about 1857, according to both of their obituaries.
I am wondering if Myrtle Weber could have been related to Elizabeth Weber Kartes?
What can I help you with?What family data do you need? Let me know.
