I have to believe she was with her mother, Salomea, if I am reading the name right off the marriage application issued in Northumberland,PA.
Since Victoria was a minor, Salomea had to give permission for the wedding. Her approval is so indicated on the application.
Now not to muddy the water, the wedding application says Victoria's father was dead at the time of the application and the mother had a second marriage to someone with the last name of Tamburski. The first name of Victoria's stepfather is not recorded on this document.
Victoria was about 16 when she married Andrew. I think it's probable she immigrated with her mother and step father. Both of Andrew's parents were deceased at the time of the wedding. Right now I have no idea if he came to the U.S. alone or with sibling.
I will keep your possible alternatives for Sasinka in mind
