I have information given to me by a distant relative who has done research on the Meath family that connects to my family. I have not verified this information, but feel he is very good in his research work.
Here is what he gave me on the Meath name that connects with the Clennan family:
Mary Meath Martin's parents were John Meath and wife, Mary Coleman Meath. John Meath was born about 1800 in Louth, Ireland and died on June 23, 1862. Mary Coleman was born about 1800 in Louth, Ireland and died on July 31, 1860 in Erin Prairie, Wisconsin. Mary Meath Martin had the following siblings, Thomas Meath, Peter Meath, Rosa Meath, William Meath and John Meath.
