Re: Seeking info re VanSycklen-VanSalee families
I'm sorry to say that I do not know much about the deWeese family. The person to whom Ferdinandus vanSicklen was indentured was a landowner in upstate New York (in or near Rennselaerwick), and it is assumed that Ferdinandus vS was to have gone to work for this gent on his Upstate property [deWeese had business interests in New Amsterdam as well and I have wondered whether Ferdinandus ever got so far up the Hudson River to have actually set foot on the upstate DeWeese property.].
My understanding is that this deWeese died during the term of the vanSicklen indenture and it appears that Ferdinandus married Eva Antonies Janse (vanSalee) at about the same time. Eva was a downstate New York resident, born in New Amsterdam and living on Long Island, begging the question how did Ferd meet Eva?.
At any rate, and I am only speculating here, it seems possible to me that if this is your same deWeese family then the famial migrations you describe may have started with the disposition of the senior deWeese's property after his decease.
In the Dutch culture then (perhaps now as well; certainly we modern Americans adopted this custon rather than the primogeniture practiced by the British back then), it was usual for property to be divided equally among the surviving children, or heirs of said children, and this sometimes seems to have lead to a certain type of diaspora.
I mention this only to suggest the context within which your Lambertus dW may have migrated away from New York.
I think I recall an article on the upstate New York deWeese family to which I refer published in the New York Genealogical & Biographical Society's quarterly, The Record. I will try to get a full cite for you and post it here.
