First let me thank the Lemley researchers who posted J. P.'s full name. Without it I would not have been able to unravel this part of the fabric of my family.
James Pinkney Lemley, also known as "Pink," married Sarah Ellen McKinney on March 4, 1875, in Shelby County, AL. Her name in the entry is listed as "McKinnie."
Sarah Ellen McKinney was the daughter of John P. and Mary Ann "Polly" Green McKinney. JPK born about 1811 in SC, MAGM born about 1822 in NC/SC. Probably NC. Ellen was born in AL about 1855 and died(? divorced?) between 1880 and 1885, probably in MS.
Here's where you will find her:
1850: JP McKinnie in Shelby County, AL
1860: Ellen is 5 and lives with parents in Bibb County, AL
1870: Ellen is 15 and lives with parents in Bibb County, AL
1875: Sarah E. McKinnie marries J. P. Lemley in Shelby County, AL
1880: Ellen is 25 and lives with husband I Pink Lemly, daughter Jennie and son Henry in Leflore County, MS. Dad lives around the corner listed as "K. P McKinney," 71, a mechanic. There may be several other family members there, too, but more research is needed.
1900: Pinky Lemley is in Carroll County, MS, with wife Mary and son 15, daughter 4. Ellen was in the household in 1880, is not in 1900, and Pink's son is 15. Hence the death/divorce dates of 1880 - 1885 for Ellen.
Thanks again to Lemley researchers who posted their info for me to find and use.
