Lillie Lilly Key Suddarth

I am looking for information, regarding a Mrs. Lillie/Lilly Key- Suddarth. From what I've found, she married a Luican Suddarth of Tennessee. Evidently, Lucian was born, in the early 1900's. However, I have no date of birth

I did find that, he may have been born in Tennessee. Considering that, most of his siblings wer born there. The birth date that I have, that may fit Lillie Key- Suddarth is, July 10, 1913. She passed away, on September 12, 1999.

Her last residence, was in Sumner County, Gallatin, Tennessee. Furthermore, if the Lucian Suddarth that I found is correct, he was a Worl War One Vet. I did find that, Lucian died in Davidson County, Tennessee, on June 26th.

Although, I have yet to find, a year of death. My Uncle tells me that, both he and Lilly may be buried, in a family plot, on private property. Any further information, would be greatly appreciated.
