Looking for information on my great grandfather and his family. MARTIN STADLER married MARY SPITZENBERGER in Oberosterrich in the 1880's. Martin had half brothers, FRANZ SINGER, and PANKRATZ SINGER. Pankratz had a daughter, BERTA. Their grandmother's name was THERESA STADLER. They grew up in Kubohuette 14 Obermoldare Bez, Budweis. in Bohemia. They worked in the cotton mill in Kleinmuenchen. Martin left Austria to go to the USA in 1883 and naturalized in 1889. I know nothing about his parents or family prior to that. Any help would be appreciated. Thank you in advance for your reply.
