I am not positive, but I believe Regina Luise Christeneck born 1735 is a sister to the artist Carl Ludwig Christineck. My Christineck ancestors came from Brandenburg area of Germany and my 4X gr. grandfather Johann Andreas Christineck b. 1684 went to Russia in 1701. He returned to Haseloff, Brandenburg, Germany by 1733 as he was widowed and married his second wife in 1733. There was a whole family of Christinecks that went to Russia at the same time. Most stayed in Russia, but my ancestor returned to Brandenburg area.
