Hello! My dad, Aaron Rusch, did Y-111 and ended up with the R-ZP136 haplogroup. Our ancestor, Nicholas Rusch, was born to an unmarried mother in Achkarren, Germany in 1853. His mother's maiden name was Rusch and there is no father mentioned on the birth record. We were hoping to uncover a potential surname for his unknown father, although from the looks of it this is a pretty small haplogroup. Let me know if anyone is interested in discussing this and I'll be glad to send more info y'all's way!
