One of those brick walls was my 3 great grandmother Susannah Baker who married Thomas Long in Kentucky 14 Dec. 1816. That was the only documentation I had for her. I thought maybe she was related to Milton Baker in Jefferson Co. Mo (where they lived) and who attended church with my relatives: Bethlehem Baptist Church. My g-g grandfather was even named Milton Long, but I couldn't find her in documentation or on anyone's family tree.
So, I decided to look at the 1810 census in Warren Co. KY where the Longs were living. The census that far back only has the head of the household named with a tally of how many lived with him (by age and gender). Knowing how my family generally married people in the neighborhood that they went to church with, I was looking for a Baker living nearby who was Baptist. I quickly found Elijah Baker with daughters the right age. He was on the page with many of the early Jefferson County residents or people who had married into my family: Browns, Longs, Dinwiddys, Gambels, Mitchells, Mothershead, Pinson.
I added Elijah Baker to my family tree with lots of ?????? indicating to anyone seeing my tree, that I'm unsure of the link. Well, that lead to his father Rev. Andrew Baker and BINGO---dna matches were appearing from others who were related to Rev. Andrew Baker. Googling him I found that he was a Baptist preacher. https://familysearch.org/photos/artifacts/8652620 I felt like I was on the right track.
