It has been awhile since I tried to research anything to do with my father's family tree, but my grandfather from Poland was baptized with the name of Stanislaw Hejdysz. I have a copy of his baptizmal cert. He was born in 1886 in Budy, Kozminensis Poland. His parents were Wawizyniec and Agniesika. He died in June of 1959. He apparently came to Canada in 1909. The last contact he had with Poland was a letter from a brother, Ignos? in 1957. At the time, the letter said all other brothers had been killed.
When he came to Canada, the authorities changed his name to "Haidysh" which we have continued to use.
Please let me know if any of this history fits with what you know of the family name. Thank-you.
