His two brothers--Samuel and John--were captains in the naval service.

His two elder daughters were married to influential gentlemen;--Catharine to Colonel Few, senator from Georgia; Frances, to Joshua Seney, member of Congress from Maryland; Maria later (1809) married John Montgomery, who had been member of Congress from Maryland, and was afterwards mayor of Baltimore.

A son, James Witter Nicholson, then a youth of twenty-one, was, in 1795, associated with Mr.Gallatin in his Western Company, and, removing to Fayette, made his home in what was later and is now known as New Geneva.

Here, in connection with Mr.Gallatin and the brothers Kramer, Germans, he established extensive glass works, which proved profitable.
* * * * * Mr.Gallatin's election to the United States Senate did not disqualify him for his unfinished legislative term, and, on his return to Philadelphia, he was again plunged in his manifold duties.

The few days which intervened between his marriage and the meeting of Congress--a short honeymoon--were spent under the roof of Commodore Nicholson in New York.
On February 28, 1793, the Vice-President laid before the Senate a certificate from the legislature of the Commonwealth of Pennsylvania to the election of Albert Gallatin as senator of the United States.
