Hi all! I am from the US taking a class in college about my heritage. I found out my great grandpa was adopted by the Schnagl family, but really was a McGuire. His dad's name was Thomas G McGuire married to Mary Margret Kroeger 1884 - 1974. (Her dad Henry Kroeger 1855 - 1930 and her mothers name was Sina 1866 - 1928) His dad was Michael McGuire, and he was married to a woman named Ellen. Does any of this sound familiar? Also, what part of Ireland is the McGuire family from??
