Hi, I want to know more info on my great great grandmother Jane L. Sleath Mcavoy. Sleath is her maiden name. I know her father was born in New York and his name is Robert. I think her mother has a maiden name of Mervine but I am not sure. I want to know more about her parents and if she had siblings. Found a census from 1860 in New Jersey. Claims Robert is father, Sally is mom. Children listed as Wesley, Alice, Isabelle, Andrew, Idah, Peter, and Jane L. Does anybody have more info????
