Thanks for that, Chris; much appreciated. I'm in Canada, so very little hope of ever seeing the cemetery, so something visual is great!
Thomas and Jane had four children that only survived a week or so after birth: Henry in 1844/5, Sarah in 1847, James in 1851, and Robert in 1849 (assumably his birth was Jane's demise).
Do you know offhand if infants were buried without headstones back then?
