I believe Eliza Tindale Covil Marine had a sister, Malvina Tindale (called Lyndell in census). They were close to Urban Frazer Wilson in the 1850 census, I believe, and Malvina was in Zorobabel Marine's household. Malvina married Urban and they had two children before he died: Anderson and Henrietta Catherine. Malvina then married Richard Taylor, a widower with children and had several more children with him.
I am descended from Sarah Ann Wilson Gillette, Urban's daughter by a previous wife.
