Does anyone know of a Zubar family or an orphage that took in my great great grandmother Sarah Ann Ruston or Robar? She was born in Charlotte,Vermont around 1839.

The only thing that I have that shows Sarah Ann last name as Zubar is on a marriage license to Abraham Ploff,dated May 17,1858 in Colchester,Vermont

Any additional help is appreciated.Please do not email me direct.Thank you.
