I read that Jean was given a land grant in New Springville (Staten Island) in 1670. This was in the obituary for Helen Seguine (Crocheron) Brown of Rockleigh, New Jersey who died at the age of 104 on August 29, 2000. This was posted to the Richmond County Obituaries at Rootsweb.
I then sent out a question the the Rootsweb Richmond County, New York mailing list concerning this. Here is what Charlene Hix sent me. She has written a book on the early Crocheron Family of Staten Island.

I am quoting from my book, "The Crocheron Family of Staten Island, NY", p. 2, published in 1980, also published in the NYGBS Record during the year
1980. I did correspond with Helen Crocheron Brown at that time.
"Jean Crocheron removed to Staten Island where he secured title to land at Long Neck, now New Springville, where, in 1670, he erected his homestead,
about one mile from the Asbury Church. In the Land Papers, volume I, p. 71, Land surveys, 1676, it is recorded that John Crushuron received 188 acres.
'Two lots at the North Side of the Fresh Kill on Staten Island, lying between the two runs of Karle's Neck and Long Neck. 100 rods in bredth by ye
meadows Ranging NE by ye common 256 rods. Bounded NW: land of Jacob Pullion and SE: Ye commons, with 20 acres of meadow next to ye Run of Karle's Neck and 8 acres of fresh meadow'. In the New York Calendar of Land Papers, volume II, 1681-1700, on 6 April 1684, there is a description of a survey of 120 acres of land, lying upon the west side of Staten Island, to the north of Long Neck and to the south of Daniell''s Neck, laid out for Jonsia
Cronsoon by Phillip Welles, Surveyor. In 1685, there is a memoranda in the land papers in which the surveyor admits his inability to locate the land
grants on Staten Island. He gives a list of names of persons to whom land had been granted and among them appears Jousia Crousoon."
