This should not be construed as being "helpful" -- it is simply information being passed on, but John Strickland, of Long Island, did get to New Jersey -- perhaps some of his family also came, or perhaps others simply named Strickland.These folks would be considered "northern" Stricklands. I can not specifically identify your Samuel. The mention of the below text is merely hearsay -- I have been unable to locate a copy.
'The Puritan in New Jersey', page 130
There is a book called the Puritan in New Jersey and on page 130 is a statement pertaining to a John Strickland. It states "If the Newark Zion began to crumble a few decades after founding, other Puritan towns in New Jersey, less zealous and homogenous, had little chance indeed to hold out. So in 1660 a certain "John Strickland" of Huntington Long Island applied to Governor Stuyvesant for permission to lead a group of settlers to the western shore of Achter Kil. A conference in which proved a failure only because they demanded, in it to religious liberty and a large degree of local self-governing in the "right to administer justice in all civil matters" without answering to the local to the provincial authorities".
