My grandmother's parents were born in Bohemia. Her mother was:
Mary Hrach born 5/1/1857 in Krastovic, Radomysli, Bohemia
and her father was:
Lawrent (Lawrence) Trcka born 8/18/1857 in Poderist, Netolitz, Bohemia.
They were married 9/29/1885 in St. Louis Missouri, U.S.A. and raised their family in the parish where they were married - St. John Nepomuk Catholic Church.
If you have any knowledge or suspicion of familial connections I would be very happy to hear from you.
