Hi there! my cousin looked up a lot of the Garritys. Here is what I can tell you.
John Garrity born about 1845, Ireland married Margaret? born in 1852, Ireland. They had several children including a son John Aloysius Garrity born Nov. 20, 1881, illinois (lived in Chicago. He married Margaret Ryan born 1885, Illinois (Chicago). These are my father Edward Ryan Garrity's parents. I don't subscribe to ancessty. com. but let me know if you have any other info, and about the other family too! Thanks.
