I grew up within 200 yards of Emma and Otto and they lived in the camp 5 region on Wierschke Rd. We do have relation to Terry and Della but Erna Golsberry lived in front of Della's place for as long as I can remember up until her death. Now Della did live on Camp 5 road but grew up on Wierschke rd across the street of Emma and Otto. Your great grandparents house has been long gone but I am now the owner of Otto and Emma's place which is still in the same place on Wierschke Rd.
Your Great grandma Emma (Brandt) married Adolph Wierschke - Adolph was Otto's Uncle and Gustav was Otto's father. Adolph and Gustav were brothers who came to the states in the late 1800's from Germany, not sure of the exact year think it was around 1881, not Poland but from the area of Germany which was Prussia prior to the German annexation. Thus the last name ending in schke not ski
Bill and Della were the children of Emma and Adolph
Gilbert, Glenn and Rose were grandchildren of Emma and Adolph
Della was first married to Buzz Buchman and then she married a Hogan after Buzz's death.
I take it that Terry is your uncle? I knew Terry quite well when I was growing up but have not seen him in years as I have not lived up there for over 20 years. Now Gilbert would be your great uncle and he had two daughters Laura and Bernadine, I think that was Lauras sisters name. I have also been in touch over a year ago with one of the Six girls who I thinks is related to Rose. Some of this history I am not totally sure of but the portion relating to Emma and Adolph is on the mark.
If you would like to know more just ask if I do not have the answer I am fairly certain I can get it for you.
