I don't have the names of any parents of Patrick Fagan born December 25, 1821 or his wife Bridget Lee born January 10, 1825. The information I have comes from their grandsons Patrick Joseph Fagan and Lambert Fagan who researched this in 1947 at Manitowoc and Green Bay, Wisconsin.
They wrote that Patrick, Bridget, Thomas and his wife left County Meath sometime between 1845 and 1849 and settled in Pennsylvania. Patrick and Bridget had 3 children born to them in Pennsylvania: Jane 1849, Thomas 1851 and Richard, 1853. They had seven more children after this all born in Cooperstown Wisconsin.
Richard and Jane, brother and sister of Patrick and Thomas came from County Meath at a later time about 1850-1854 and brought their widowed mother ( no name listed for her) They went to Pennsylvania and then went to Manitowoc County sometime between 1855-1860. The brothers homesteaded land and built houses. Richard built a house for himself, Jane his sister and their mother. The mother died sometime in the middle 1860's and is buried in Francis Creek cemetary in an unmarked grave. Soon after the mothers death Jane married Patrick Lyons.
Here is a bit more information I have on the Keenan side. It is possible the name has a different spelling. Nickolas Keenan was born in Ireland May 1, 1769 and his wife Jane Murry was born in Ireland September 29, 1782. They had 3 children born in County Meath Edward 1808, Richard 1814, and John 1820. All of these died in Francis Creek, Wisconsin.
John Keenan born in County Meath June 24, 1820, (son of Nickolas and Jane) married Margaret O'Brien. Margaret O'Brien was born March 17, 1830 in County Cork to John O'Brien and Mary McCarthy. John and Margaret had 5 children born in Cooperstown, Wisconsin, Jane the first child was born there in 1858.
All of these people were Catholic. I'm guessing they had information and connections from other relatives leaving Ireland to help them first start in Pennsylvania, then move on to Francis Creek Wisconsin and settle there.
Thank you to everyone who is reading this and offering help and suggestions!
