I do not know any of his siblings names. All I know is that his siblings and parents were all born in Czech then they all came to Texas in the early 1900 and Joe and Anna had their last child in the 1920's. My grandfather married in Texas and moved to New Mexico. Where he had 4 children and adopted 1 son. When he died I was young but I remember 3 or 4 of his relatives came to his funeral. They were blonde.
