Thanks again, everyone. I missed Robert in the message. He was wounded in 1915, but went on to a B.Sc. in 1918. I see that de Burgh and Burke are equivalent, but I don't understand the importance of the de Burgh name. Anyway, I will hope his children are on-line some time as I would love to know more about the family.
Robert, the brother of Henry, died in Ireland so he is not missing in NZ. Henry's uncle Robert is my ggg grandfather, uncle's son Robert went to Illinois, USA via upstate NY, and uncle's grandson Robert went to upstate NY. I'm from uncle's daughter who went to upstate NY.
