Cindy - The 1st Earl had a sister who married someone named DuPre and that's where his son's name comes from. Records seem to be very scanty on this bunch as no one seems to know the name of either the 1st or 2nd Earl's wives. A cousin of mine did a huge amount of research on the Alexanders, because there were some very tantalizing hints in our family history suggesting a link with the Caledon Alexanders. There were four brothers in County Tyrone/Armagh Ireland, James, David, William and Patrick - the first three came to Canada, Patrick stayed in Ireland. Although they were listed as "flax growers" in Ireland they arrived with a great deal of money and were able to purchase substantial farms in Ontario. They were also very close-mouthed about Ireland and why they came. Certainly there has always been a aura of mystery around this. However, whenever Viscount Alexander was named governor-general of Canada, one old aunt insisted that he was a cousin. Certainly a lot of the same names seem to recur in both families. My cousin who did the research hired someone in ireland to trace all this, but records are so scanty or missing that he wasn't able to come up with much. My cousin went to Ireland at one point and went so far as to march up to the present Earl of Caledon's door and announce himself as a possible long-lost cousin. (He's not exactly shy!) The Earl was very gracious, but unable to shed any light on the situation. Anyway, here are the dates: David b. 1786 William (my ancestor) b. 1802 Patrick b. 1800 James b. 1803 the 1st Earl of Caledonreturned from India in 1772, at the age of 42 with a fortune in hand. his son DuPre was born in 1777, his son and heir was born in 1812. When the 1st Earl died in 1802, his estates were valued at 600,000 pounds! So - it's very tempting to leap to the conclusion that there is some connection (an undiscovered marriage? an illicit liaison????) I have lots more info on my branch of the Alexanders in Canada. If any of this fits with your data, please let me know.
