Hi Jeri: This may be a longshot but, did any of your Yunkers live in the East St. Louis, IL area? My Bro-in-law's grandparents were; Jacob Yunker who married Minnie Helbig in Belleville, IL on Dec 7, 1903. Jacob's parents were Jacob Yunker (B-Germany about 1863) and Charlota (Bensby?). I just started to research this family for the benefit of my nephews and niece. If any connection, let me know and maybe we can help one another. Sincerely, Bob Barber
