I am also looking for info about the Trocha's. My mother-in-law is a Trocha and her grandfather Micheal Trocha Sr. was born 24 Apr 1886, in Austria. His family may have come to America about 1911. He was married to a Julia Straka also born in Astria.
This is all the living family can remimber, if you know more or this sounds like we could be the same family please keep in touch via email.
