I'm confused...I thought Joshua's wife Melleney's father was Thomas Warne. Joshua & Thomas Warne made stoneware pottery in South Amboy. They were a father-in-law/son-in-law team. I think Joshua Warne was Thomas' son. I would love if you found out something different since Joshua is in my line of Letts too (born to Elisah Letts in Perth Amboy) and I'm trying to find out as much about Joshua as possible.
