It's been a while since I've had time to work on my research, but I've finally gotten back to it. Ancestry had a special deal for a six month subscription, so I bit the bullet and joined. I found a 1930 census record that I hadn't seen before.
I was hoping to find a marriage record for my grandparents, but can't find anything. I don't have any information on where or when it took place.
I should probably spend some time learning how to navigate Ancestry. I went in cold to do this search.
