Thank you Milliepede for your efforts. We are aware of the baptisms of these 8 children. It was interesting that Janets first child Mary (to a different father), was excluded when 6 were baptised at one session.
We had also looked at the Charles Glossop transported to Van Diemens land (Tasmania) aboard the Marion, but the london county court records and Marion's records show he was born in London, was born about 1818 and was literate. My GGF was , we believe born in Isle of Wight about 1804 and only ever signed his name with an "X".
We had considered that our info was maybe incorrect, and that the Charles on the Marion was the right one, but there is more evidence to suggest the I of W Charles is the right one, and nothing to link the Marion Charles.
As to the Charles Jerrison transported, I simply have no idea. Maybe William Glossop and Elizabeth never married and Charles was their son, and William abandoned her. I guess Charles could have taken the Glossop name once he was in Australia.
As an obviously experienced family detective, could this make sense to you?
To date I have no info about Eliz.Jerrison and her life after Charles birth.
Do you have any further info about this Charles Jerrison?
stay well and thanks again
