The "Kukiņi" homestead located in Košrags was mentioned in 1680 chronicles for the first time. Košrags is considered as one of the newest of the Liv villages, as it was formed in the 17th century. By 1770 there were four old farms in Košrags (Kine-Dīķi, Kūkiņi, Tilmači and Žoki). Two tenant-farmer habitations existed in 1896, and another seven habitations after 1905.
The houses in the village were built rather densely along the two roads:
an old littoral road connecting all 16 Livonian fishermen villages at that time;
the fishermen's road leading from the littoral road - it connected the villages with the working place near the sea.
These roads have preserved their ancient shape till the present day.
