I am looking for descendants of James Flood born 15 Aug 1820 in Rathgeran (my great great grandfather) and his brother Michael Flood born Sept 1828. (The 1905 obituary of James Flood noted he was born in "Rathgarren County Carlo". I believe the town name in the Obituary was spelled phonetically and is actually Rathgeran.) They both left Ireland at the same time and traveled together to the US in 1848. By 1860 they are both living in farms next to each other in Woodbury, Cumberland County, Illinois (this is near Effingham Illinois.) I don't know their parents names but am thinking their father's name was most likely John Flood since both named their first born sons - John. One John Thomas Flood and the other John Henry Flood. They were Catholic. Any additional information about their ancestors living or not living would be appreciated.
I have looked in the transcribed records online for the Borris Parish but did not find their records there. I have found the records in the Tithes for John Flood of Knockymullgurry. I have also seen the voter records for a John Flood in 1838 of Knockymullgurry. I have looked at the 1901 and 1911 Census records for Floods in Ballyglisheen. Any additional suggestions of places to look would be appreciated. Any connection with living Floods in the area would be appreciated too.
