This information is from a decendent of this Blackler, Wilma Blakely Abplanalp She states in one document that he was born GB and came to the US and fought in the Rev war with Bourgoyne. In another document she says he is the decenden of a John Blackler who died enroute in 1630 on the Hopewell with his brother, Samuel. His wife and three sons ended up in various East coast states. One of these John, Jr. is indicated as this John's father. Improbable based on the dates. Difficult to go back past here cause of last name variations.
