Yes, that would be the correct family. I am Genevieve's granddaughter; George & Theresa's great-granddaughter.
As far as the Jilk family, I have no information beyond George. Siblings, parents, ancestors, origins, et cetera.
For the Rietz family, I have some information, but am not sure if it is correct. I have that Theresa's parents were John Rietz (1868-1930) & Margaret Weiskirchen b: September of 1871. They were married May 3, 1892 in Fredonia, WI (Ozaukee Cty.)If those are Theresa's parents, I have archived that Margaret's parents were Joseph Weiskirchen & Elizabeth Grabinger. I also have listed that John's parents were John Baptist Rietz and Anna Marie Knipfer; Maternal grandparents being Konrad Knipfer & Ursula Melchor.
Also, there is question on the spelling of the last name Rietz. I have asked my grandma a few times, most times she says it is spelled Rietz, but once in awhile she thinks it was spelled Reitz. Any clarification would be great!
Thank you for your help!
