Sjöcrona

The family's ancestor Torbjörn Eriksson lived during the late 17th century in Landskrona, Skåne, where he was a shopkeeper,[1][2] and where his son Severin was born in 1700 and died in 1766.

Anrep states that father and son called themselves Cronsjoe.

Severin Torbjörnsson had a son, Ludvig Cronsjoe (1726-97), who received the title of assessor.

The latter had with his second wife, Ulrika Bush, a niece of Lars Gathenhielm, a son named Cornelius Alexander Cronsjoe (1767-1824) who became lantråd and who in 1819 was knighted[3] according to § 37 of the Constitution 1809, whereby the nobility only went to the head of the family.

[4][1] The following year, the family was introduced to the House of Nobility with number 2273.
