Thanks so much for your response.Your idea that the Joseph who obtained land in Danby Vt might have been Joseph JR is a good one that I had not considered.It is likely Joseph SR was in Great Nine Partners because his dau,Katurah,married there in 1762,so I had just assumed it was SR who obtained the land in Danby,but perhaps JR is more probable.I have the impression that many/most who obtained those grants in Danby did not actually settle there.Do you have any evidence that Asa, Joseph, or Samuel actually settled in Danby?What I did find is that Asa Alger settled in Pawnal and Manchester VT,but could find no evidence of either Joseph or Samuel in VT,though my search has not been exhaustive.Do you know Asa's parentage?Samuel is sometimes said to be Samuel,son of Robert and Elizabeth Innes Alger, but if so he did not seem to settle in Vermont.
My real interest in Joseph and Mary Huntley Alger is because I think they might be the parents of: Ruth Alger m. Simeon Calkins in Sharon CT in 1755 (In 1761 they settled in Lebanon Ct joining the Goshen Church) Sabra Alger, b 26 Sep 1741,also joined the Goshen Church at the same time as Ruth and her husband in 1761,married John Closson in 1764 and migrated to VT (first Hartford,then Thetford).
Apparently the early settlement in Sharon CT,across the river from Great Nine Partners,had some association with that settlement and there are no other Alger records in Sharon,but the Calkins family was numerous in Sharon. There are also no other Algers at Lebanon CT so I assume Sabra had probably accompanied Ruth and Simeon Calkins when they moved from Sharon to Lebanon in 1761--all joining the Goshen Church at the same time.
The large gaps among the births of Joseph and Mary Huntley Alger's proven children suggest there were others and I have read that they had 12 children,but who were they and is there other evidence.There is surely some other information on Joseph Alger someplace.He could have died in Dutchess Co., of course.I think he only appears in tax lists of Crum Elbow from 1759 to 1761. Katurah married at Great Nine in 1762.And 1761 is the year Ruth Calkins and her probable sister,Sabra,joined the church in Lebanon,apparently having come there from Sharon CT (across the river from Great Nine).And the Danby grants were in 1761.Lots happening at the same time.
If you have other clues or information,I will be most grateful.Thanks.
