This is the first time I've seen a Shulke name posted. I'm not sure if there is any relation but I am hoping to finding siblings/cousins to my great-great grandfather. I am a Shulke (spelling has varied with each family member I've talked to Schuelke/Schulke/Shulke).My great-great grandfather was William Shulke (b. 1824 approx.) who married Caroline Manthy.The were both from Posen.I don't know the town but one of their children was born in Leubsiz, Germany.William had six children, Wilhelmina, Emily, Emma, Albertina, Hulda and Jules (my great grandfather).The settled in Newton, WI.I haven't come across any other Schulkes in my search.My grandfather and his father were only sons.Other famiy names are Polfuss, Shaefer, Buchhotz.Good luck on your search.
