Hello from Minnesota! I read about your interest in the Goldbeck/Jeseritz link and thought I would try to help out. I am Greg Jeseritz, son of Harold and Lila(Mock) Jeseritz.Harold is son of August and Matilda(Munsch) Jeseritz.August is son of Rudolph Sr. and Augusta(Grams) Jeseritz.
One of Rudolph Sr's sisters was Pauline Jeseritz who married a Mr. Goldbeck (accourding to my family tree book) who I assume to be Gustav Adolph Goldbeck.It says that Mr. Goldbeck stayed in Germany...Pauline died in 1905 she had 2 granddaughters, one whow was Elsie Wolf.It says that Mr. and Mrs. Goldbeck lived in Essen and Bochum, West Germany, near The Netherlands about 100 miles SE of Amsterdam.Pauline's 3 sons died in WWII.
There are still many Jeseritz's that live in and around the Wood Lake, MN area.If you would like any more information please contact me.
