Joseph Maxwell c1808 Royal Engineer died surveying for Knight of Kerry c1840
Joseph Maxwell was born in Ireland according to one daughter's Ontario census record and in Scotland according to another daughter's Ontario death record.
I do know that Joseph (or John) Maxwell died before 1844 when his wife Elizabeth Bond emigrated with their 4 children to Canada. He was killed while doing a survey for the Knight of Kerry in Ireland but I don't know exactly which year.
Joseph and Elizabeth's children were Jane born 1830 Ireland died Toronto 1912, Matilda born 1835 Ireland died Toronto 1920, John born c1836 Ireland and died around age 20 and Elizabeth born 1838 Ireland and died Toronto 1909.
Hopefully there is someone else researching this Maxwell family that can shed some light on Joseph.
