I know this is a very old post but thought I would reply in case anyone else comes across it as I did.
I have documented info on Eva Leona Phagan and Edward Porter in my tree on ancestry.com if anyone would like to take a look at it. My big road block is figuring out who Eva Phagan's father was. I know her mother was Grace Jones but I can't find her father's first name anywhere. If anyone has info they would like to share, I would greatly appreciate it.
