He was past his thirtieth birthday when he married skipper's daughter Geertruy Switts in July 1765. The marriage may have only produced one daughter who was baptized in 1766 at the Albany Dutch church where Myndert was a member, pewholder, and occasional baptism sponsor.
Myndert Roseboom was a prominent merchant and a resident of Albany's first ward. In 1766, he joined a group of Albany men in signing the constitution of the Sons of Liberty. In 1771, he was elected assistant alderman for the first ward.
Previously, he had been an officer in the provincial militia. In 1759, he was identified as a Major with the New York provincial regiment at the seige of Fort Niagara. In August 1775, he was nominated to be colonel of the second regiment of the New York Line. He seems to have declined the commission "due to his age."
In 1776 and 1777, he was elected and served as a member of the Albany Committee of Correspondence for the first ward.
Later, he served as a commissioner of sequestration for the middle district of New York and was awarded a land bounty right in conjunction with the first regiment of the Albany county militia.
Myndert Roseboom's personal property was valued on the Albany assessment roll in 1788. In May 1790, he was left a monetary bequest in the will filed by his father. His household was not configured on the Albany census although he may have been accounted for under the household of Hendrick Roseboom.
