Hello. I am trying to find the family of Katherine Davern. She was born in New York and can be found married to Frank Donovan on the 1930 and 1930 Buffalo, NY census. She was born around 1891. She passed away in Buffalo in Aug 1983. She was my great grandmother. I haven't been able to find out who were her siblings or parents. Any assistance would be helpful. Thank you!!!

PS
I did see a 1900 Buffalo census with a Minnie Davern and a Catherine, born around the same time, is listed. But I am not sure if this is her. Thanks
