MitoSearch.org is a free public service from Family Tree DNA that allows individuals that have tested their mtDNA with different companies to make their results available for comparison. I have my results posted at MitoSearch.org and hope to find matches.
My Great-Grandmother is Mattie Belle Peters. Her parents died in a train accident when she was young. I don't know her parents' names or where was the train accident. She was raised by an Aunt and Uncle. I don't know their names. Census records and death record say she was born about 1874 in Michigan. Michigan does not have a birth record.
I do know Mattie Belle met and married my Great-Grandfather, William Lyon, in 1892 at Sedgwick, Lawrence County, Arkansas.
Post your mtDNA and maybe we'll find our ancestral connection.
