O'Connor Help

I am researching my father in laws ancestry for him.

I have reached a dead end in my search.

Jeramiah O'Connor married Bridgett Fields. He was born 17 Mar 1853 in Ireland and she was born Birth 19 Nov 1862 in Ireland.

I know that had a least 1 son. John Lawrence O'Connor born on 5 Jan 1884. From some cenus records it appreas they also had another son Michael O'Connor who was 2 years younger than John. John from everything I found was born in Castlegregory, Kerry, Ireland.

I have nothing more on Jeramiah. There has been many different spelling for his name in my findings.

I do have Bridgett's parents names though. Her father was Richard Fields (birth: 1821) and her mother was Mary Reegace (birth:1822). That is my dead end on her.
