Hello, Malvina was living with her parents in Coxsackie, New York when the 1870 census was taken. On Nov. 15, 1872, Malvina Gregoire and Edmond Perrier had a son Adelbert in Troy, New York (not sure if Albany or Renselaar). So looking for the marriage between 1870 and 1872, and thinking it is in Troy or nearby. Desperately hoping to find this marriage as it has been a brick wall for many years. Thanks so much. Peggy G.
