It could be Catherine Penny,she may have been married twice.I did not realise how time consuming this ancestry stuff could be.
I thought that there were 2 Buzzard families living near each other with a William as the head.Until I worked out that Anne had died and he had then married Eliza,whose husband Robert Reynolds had also conveniantly died!!.
Both families were almost neighbours,so would have known each other.
Also Eliza Reynolds whom William married after Annes death had 4 children herself,and it looks like they were shared out amoungst the Buzzard family and unofficially adopted.
So you could have cousins on your half that are unknowingly adoptees of Eliza Buzzard/Reynolds.
It looks almost certain that John Buzzard ended his days as Chapel Keeper (caretaker)to the Guards Chapel in Bird Cage walk.and this would explain how Catherine was given the relative luxury of an Alms house,conected to the Regiment and Chapel in St Ermins Hill SW1.
Here she lived with 2 of Williams and Annes children.Emma and Sarah
Another son of William and Anne,John,was put into the Greycoat workhouse school.
Henry stayed with his mother and father.
