I don't know if Acklen is her married or maiden name, though.
Her son, William Thomas Acklen (4/8/1840-3/9/1915) is my ancestor. William married Mary Rebecca Burleson (1850-1891).
I don't have the birthplace of Mildred or William, but I know that William's daughter Sarah Corina Acklen was born in Nashville, TN 2/12/1867. Sarah married William Smith Biles also of TN. They were married in Buda in 1887.
So, Mildred, William and Sarah are all buried alongside each other in our family plot.
Please contact me. I just forwarded a similar message to Trish, too.
