He married Lucia van Mollem in 1704 in the Waldensian church in Utrecht, and they had one son, Hendrik (1709–1738), and one daughter, Jacoba.

In 1718 he became the owner of the fine Nieuwe Herengracht 99, well known for art connoisseurs due to the five gigantic hunting still lifes by Jan Weenix.

In 1722, Hendrik Gravé became schout-bij-nacht and was the following year put in command of a Dutch expedition against the Algerian pirates.

[1] Due to a problem with his foot (called podagra, possibly meaning gout), Gravé had himself tied onto his chair when there were storms.

After years of illness, he died at 78 and his funeral, as described by Braatbard, was an event of the first order, with the procession lasting three and a half hours.
