Re: Susan Cozens family Bible
The only way the name is spelled in the Bible is "Cozens".
The frontispiece contains a list of the names of deceased children from 1803-1811, so your gt grandfather, etc. wouldn't appear there. The last entry in it is a pencil notation of Susanna's death in 1816, written by an anonymous relative (unsigned), in 1847.
The Bible was owned (and signed) by John Cozens, although it was Susanna who made the list.
Not due to damage, the written annotations are a little hard to read.
I would be happy to try to take a photo of the frontispiece, if you want.
