Looking for information on Thomas John Brennan

[Noel B]

Thomas John Brennan married Catherine Butler In the Muckalee Church on the 21 February 1830, Present were Martin Brennan Mary Butler and others. They had to my Knowledge three children, John Thomas, born around 1832, Mary Catherine, born around 1833, Tobias Brennan born around 1834. I am trying to find out if there were any other children, and what become of thomas and Catherine, and if they had any other children.

As the dates you are interetsed in finding are before the start of civil registration you will need to look for church records (if they still exist).
You can search LDS catalogue at www.familysearch.org and see if they have microfilmed the records you need. If so you can order them from your local LDS library for a small fee and view them at that library.
