seem to missed out the youngest son's name - Henry (think = James Henry in census)
I photo a few subsequent pages of school education committee minutes - it would appear that she was the teacher, her husband helped in some items (the committee agreed to pay cost of whitewash so he + she could whitewash + paint school room over Xmas holidays - she appeared to be paid £5/month for first couple of years then £5 16s 8d - possibly he kept on his pharmacist job but he doesn't appear in any directory so maybe he was semi invalid.
Anyway you now have his first wife's name + death - I think the Fielding connection is via his father's connection with the Oddfellows - look up fielding on ManxNoteBook
