Does anyone have any information on Anton Koller in Louisiana. He married Mary Theresa Whalen(?). They had a son named Louis George Koller who married Cathrine Uhlein, December 22, 1885 in New Orleans. Louis and Catherine eventually moved to Texas. It is possible they also had a daughter named Caroline. I've found a census entry for Anton Keller with wife Mary, son George, and daughter Caroline, but have been unable to find the family again. I think this may be them.
