Susie Stephanca Hatvany/Fredrick Whilhelm I Uhlenbecker

Does anyone have information on the family of Susie Stephanca (Hatvany). She came from Austria Hungry and I would like to find her family history.

I am also looking for the family history of Fredrick Wilhelm Uhlenbecker His family came to America from Germany before WW1

I am also looking for family history of Margaret Mary Coyle who's family came from Ireland before WW

I know nothing about My mothers side of the family and my Father's Mothers family
