Thomas Dean last referred to, had only one child, a son William Dean, Esq., who graduated at Columbia College 1855, and has a law office in New York; lives in Tarrytown. A son Bashford Dean is a graduate of the College of the City of New York, where for a time he was engaged as a tutor, and now has the position of Professor of Biology at Columbia College, so rapidly has he been advanced by reason of his high qualifications in the branches of study which he has made a specialty. He has twice been abroad, once as the special agent of the U. vS. Commission of Fisheries, where he acquitted himself with honor. Professor Bashford Dean was recently married to Miss Dyckmau, the daughter of Isaac M. Dyckmau, Esq. , of the old Kingsbridge Dyckman family. Wm. Dean also has a son Thomas and a daughter Llarriet M.

This much to show that Sergt. John Dean of the Revolution has posterity as well as ancestry. That there was cause for his being the hero and patriot that he was.
