There are a lot of unanswered questions (mysteries) on this lineage. Oscar Giuseppe Lewis was a baptist minister. He married Ella Sneed born in Alabama around 1869. They were married in Tennessee in 1889. They had a daughter (my maternal grandmother - Ella Pauline Lewis) born in 1904 in Alabama. Ella was buried in Tennessee but husband Oscar did not place a marker on her grave. Oscar was later shot ("execution style") in the back of the head. He is also buried in Tennessee.
And this is about all the information I have about them.
