So it's safe to assume that Samuel died between 1906 (after Gladys was conceived) and 1908 since Minnie had been married to Joseph Slate for 2 years at the time of the 1910 Census. Maybe that will help for the hunt on his side of the family! Thanks!
My only concern now is that I have that Gladys was born in KY not TN as stated in the Census. I have noticed that there are many inconsistancies from one census to the next. Ages vary along with spellings and other info. Do you just excuse that conflicting info because everything else matches?
