Henry Kirke White Welch (Jan 1, 1821–Nov 25, 1870) was an American lawyer and politician.
He taught in Brooklyn, Connecticut, from October 1842 to March, 1843, when an affection of the throat compelled him to desist.
In the autumn of 1844, he returned, but finding his throat still sensitive, went South again, and spent the next two years teaching in Montgomery, Alabama, at the same time studying law.
Welch married, March 24, 1852, Miss Frances Louisa, youngest daughter of Professor C. A. Goodrich, of Yale College.
His wife died Dec 2, 1855; and he remarried three years later, Miss Susan L. Goodwin, of Hartford, who survived him with four sons and a daughter.
