When tracing back my family, I found that my great-great grandfather, Allen Franklin Raines was married to a Mary E. Murdock of Alabama, whose father was Robert W. Murdock. R.W. Murdock was born in Georgia around 1840, and his wife's name was Hannah (born about 1848). Hannah died before 1910, and RW died before 1920.
Robert W. and Hannah Murdock's children were:
Mary E. Murdock (born about 1868, married Allen F. Raines Sep 09, 1886)
Hannah M. Murdock (born about 1870) Robert H. Murdock (born about 1875)
Mary E. Murdock-Raines died sometime around 1930. Her descendants (Raines', including me) now mostly live in Mississippi. I don't know the fate of the rest of their family.
