I have a gggrandfather Theador KOSTELLO and wife Palagia KEY from Galicia-Austria todays southern Poland near the cities of Tworylne and Zubensko. They had daughter Catharina(Katherine) b.1882 and Anna b.1896. They came to America some time before 1903. in NY, NJ, and PA. Some of the family has gone to use the spelling Costello. Any information on other Kostello of Austrian-Galician-Polish descent would be appreciated.
