I have very little information on the Downs family other than what I have found to date. The following was found on an Ancestry.com family tree, so you have take it face value until it can be verified.
Name: Thomas Matthew Downs , Jr. was born 22 MAY 1840 in Marion County, AL and died on 10 DEC 1900 in Anderson, Limestone, AL He is buried at Legg Cemetery in Limestone County.
His 1st wife was Margaret Roberts and she was born 22 SEP 1840 in Tennessee. Date of her death unknown. They married 5 MAR 1865 (location not known) and had 9 children between 1865 and 1884. included in those children are Lillian N Downs born 1871 in Giles County, TN and Thomas L Downs born 1873 in Giles County, TN.
His 2nd wife was Eliza Eveline Coffman and she was born on 15 DEC 1867 in Limestone County, AL They married on 4 APR 1889. They 6 children, one of whom was Calvin M. Down, the husband of my great Aunt Elsie Cobble.
I have some census information but nothing significant. When I posted sometime back, I had 2 purposes: Locate any of Calvin and Elsie living descendants and second, verify what little information I have been able to find.
I will share with you what I do have and some possible leads for additional information, Feel free to contact me:firstname.lastname@example.org
