Thanks for the information. I have come across this Luke Murray in my research and I have to be careful not to get the two families mixed up. The similarities (dates) are interesting. As far as I can tell, your Luke and my Luke are from two different families. My 3x g grandfather was a native of Roscommon, Ireland. His birth does seem to be around 1825 and I can confirm his death in 1898. He and many family members are buried in Saint Patrick's Cemetery in East Greenwich, Rhode Island. If you do find any info related to this Murray family,I would love to see it.
I did find a book at the RI Historical Society Library that tells the story of your family. Title: The Murra-Lohan family: thier Irish Roots and American homes Author: Mary Corcoran Call Number: Reading Room: CS71 .M9785 2009
