He was the father of naval officer and plantation owner on Saint Croix in the Danish West Indies, John Christmas.

The family had originally come from England, but rose to prominence in Ireland as High Sheriffs of Waterford and MPs.

Hanne was the daughter of Johan Friedrich Heinrich, an advisor to the king and former director of the Danish West India Company.

Their eldest son Admiral John Christmas (1799–1873) was acting governor of the Danish West Indies, and died on his plantation Peters Rest on St. Croix.

Their youngest child George Beresford Christmas (1800–1867) also spent time in the Danish West Indies as a naval officer.

[1] Their great-grandson, Walter Christmas, later played a large role in the sale of the islands to the United States.

[1] She was married two more times after that, first with doctor Johannes Lorenzen (1774–1807) and then actor Niels Simonsen, before she died only 37 years old in 1808.

John and Anne Christine lived as a couple at his country house Høveltegaard, presumably until 1810 or 1811, when both of them moved separately back to Copenhagen.

It is a distinctly English-inspired building, which he, according to Sophie Dorothea Zinn's memoirs, refurbished in 1793 with all British interiors.

In 1798, Christmas bought a newly constructed property at the corner of Rådhusstræde and Brolæggerstræde from Andreas Hallander.

[4] Gyldensteen’s Gaard, a beautiful house at the corner of Bredgade and Dronningens Tværgade, which has since been completely rebuilt into the Phoenix Hotel, was incorrectly identified as John’s house in the early 1790’s in a publisher’s footnote in Sophie Dorothea Zinn’s memoirs.
