It is based in the village of Husby on the southwestern part of the island of Tomma in what is now Nesna Municipality.
Anders Christensen the younger (1751–1821), a shipper and a tradesman, and otherwise a great-great-grandson of the noblewoman Margrete Jonsdotter Benkestok, started in 1806 buying properties in the parish of Lurøy.
He bought altogether twelve parts of the farms Grønningen, Kvitvær, Lunderøy, Måsvær, Sandvær, Sengstrag, Sør-Nesøy, and Trolløy.
After Christensen's death his widow Anna Catharine née Bernhoft continued buying properties.
[1] In 1910 Nathalie Christensen married Karl Olaf Johan Karlsen Gidtske (1865–1948), a priest and a cand.theol., who thereby became the owner of the Husby Estate.
When their son Kaare Krey Gidtske (1912–1995) took over the estate in 1944, it had been reduced to about 50–60 farm properties (from the original 190).
