Welcome to the Rostock Family Tree!


The Rostock Family includes the descendants of Peter Samuel Nilsson & Catarina Petersdotter, founders of Rostock Farm in Småland, Sweden. Peter & Catarina settled the farm about 1845 in the rural community of Rostock where they were known as the Rostock Family. Their eight children and descendants form the branches of the family tree.

Rostock Stronghold
Rostock Stronghold

At Rostock there are remnants of a stronghold. The stronghold was situated on the narrow neck of land between Rostock and Grimmansmåla lakes where the important trade route from Blekinge passed the Wärend border. In the middle ages there lived a ruler named Algut. The stronghold was built on this islet to protect the extensive real estate holdings Algut possessed, which was the whole of Algutsboda parish.
