I have spoken to Marilyn Van Dyke, Town of Queens bury Historian, who
states that she has heard about the Quintuplets but cannot verify
anything more than was posted here. The Irish cemetery is over near the
border toward Ft. Ann but does not believe there is any mention of the
children (if they were Irish children). She has no further information
on them.
Albert Fowler (answered my email) of the Center for Folklore and History
Room at Crandall Library in Glens Falls, Queensbury, NY stated that he
could not find anything in their collection. He would be interested in
any information that might be found about them.
