There is a father-son pair, both named Nelson Gilreath, and it is uncertain which is the song writer.
The copyright notice on Will You Meet Me at the Fountain? reads
Copyright, 1894, by Nelson Gilreath, Cartersville, GA. The 1894 date indicates the author is the man whose tombstone reads
Nelson Gilreath, Sr., lived from 1868–1936, buried in Malakoff, Texas (Findagrave record).
Unfortunately, he has no known son named
Nelson, making the Sr. title questionable. His father, also named Nelson, is buried in Cartersville, Georgia, but died in 1889 (shown by both tombstone and newspaper obituary), too early for the 1894 copyright (Findagrave record).
We conclude that Nelson the younger is probably the song writer, though we are open to evidence showing otherwise.
If you can help with any of these items, would you ?
