I would look into Gabriel Marselis in Netherlands as a posible candidate. I saw some good info on this under Pieter Marselis in a community web page. There is a thought that he had several sons who came to the dutch colonies. Hendrick who was established as one of the Staten Island group as you have read and Pieter, and possibley Jan Marselis who emigrated later and will be found on the ship lists.
I am of the OPINION that the info on Ten Eyck is incorrect. When you look at the naming records you see that coenradtsen is a very rare patronomic.
When you dig in the dutch records you see that Houghtaling used the Coenradtsen in some records and not in others. There may be a Ten Eyck connection but I have not seen anything in there lineage on line that seems to tie in. Apparently Ten eyck means tall oak or the like. and may refer to a geographical descriptor or even be a way to deferentiate the two as Hougtaling was in Kinderhook, Kingston and Coxsackie and Albany at various times and it seems that they must have been comtemporaries for at least some time.
Henry Marselis co-signed a note for his son inlaw Mathias Coenradtsen Hougtailing for a farm behind Kinderhook. Later they moved to Coxsackie and purchased a large track there. He lived with Mathias and his daughter until his death. He was married to Tryn or Catryn Vandenberg. However, it appears as though she died shortly after he fled Staten Island and he remarried. There were at least two children from that union. From the birth order and naming of the Houghtaling children. His wife name of Maria Hendricks indicates either his mother or hers was Maria depending on whether her sister was born first.
I believe that Jan Marselis is more likely to be kin as Henry (Janz)Marsleis is the name used when he purchased his yacht with Van Alstyne.
Anyhow the sources get thin that far back and the patronomics and nicknames used tend to obsure conections and confuse associations. The Albany church records are as source and the NYC dutch refromed church records as as well. If got through the years you can see birth records for Hendrick Janz. There is a website GOEWey who claim Hendrick as part of their line.
I would be thrilled if you get more on the early dutch pre-emigration side that you can connect. As my line connects heavily with Houghtaling and Henry Marsleis. Rykert Janse Vandenburgh married Mathias C. Houghtalings daughter Tynjte and a bapitsmal sponsor of one of children Jan Marsleis's dauther Judic.
It also appears that Houghtaling had a close relatioship with Martin Gerritse Van Bergen who was the commise for the Van Rensslear's for a while.
