Jean de la Montagne and his wife Rachel de Forest, early colonists in New Amsterdam, are ancestors of mine. See here, under numbers 15854 and 15855, for details.

While the parentage and ancestry of Jean de la Montagne is unknown, the ancestry of Rachel de Forest (and of her brother Isaac de Forest, founder of the American de Forest family) was presented by J. W. de Forest in The de Forests of Avesnes [New Haven: Tuttle, Morehouse & Taylor, 1900], and is summarized below (this reference is cited as "JWDF").

Another source utilized is the website of the "Society of the Descendants of Johannes de la Montagne", http://www.delamontagne.org, in particular the information extracted and displayed in the WorldConnect databases at Rootsweb, specifically here.

The numbers in parentheses are numbered from me.
