Although she was born in Germany and immigrated to Russia, I haven't been able to positively connect her to her parents yet. She should show up in the Kulberg Reports or in one of the early census records, but so far I have not found any possible matches. These are the only Schreiners that appear in the Index of the 1767 Volga Colony Censuses. 
I don't have a copy of Band 2, the volume that would include the Colonies of Kraft, Kolb, and Krasnoyar, so I can't confirm if she appears as a child in any of those records.  She is not listed as a child in any family in the Norka, Rohleder, and Seelmann records.
The Colony of Kraft was close to Holstein, where her first husband was from, so that may be the logical place to look next for a match.
She married first husband Christian Vogel before 1782 and the couple had four children:
She may have had older daughters who were already married and living in other households by 1798. If so, they were not living in Franzosen. The only similar surname to Vogel in Holstein in 1798 was Vogler and they were all male adults. They may have been relatives of her husband. 
Her husband Christian Vogel died between 1794 and 1795, and by the end of 1795 she had married second husband Christoph Kober. She and Christoph had two children by 1798:
