Suydam - Stout connection

My ancestor, Adelaide Stout, married a Mr Suydam some time after 1800, probably closer to 1810. The family story says Mr. Suydam was the partner of Andrew Varick Stout, born 1812 (brother of Adelaide), who named his third son, my direct ancestor, Joseph Suydam Stout (born 1846) after Mr. Suydam. But I have not been able to confirm the story of partnership, or discovered the first name of Mr Suydam.
