Christian Ludwig Horlensen, a craftsman (Handwerker), and his wife Maria settled in the Volga German colony of Dobrinka on 29 July 1765. They are recorded there on the 1767 census in Household No. 29.
The 1767 census records that Christian Ludwig Horlensen came from the German town of Reval in Estland [today Tallin, Estonia].
There do not appear to be any surviving male descendants of this surname, so it does not continue among the Volga German colonies.
