I have a Daniel Wilcox who married Phebe Arnold in Northern NY. I cannot find her dad. Perhaps he is Edward Arnold in Ellisburg NY.
I am from Northern NY and am very familar to the towns Ellisburg is very close to Worth which is where they lived.
She lived 1799-1870. I'm wondering if she is the unknown daughter listed in the descendents. She does meet the profile. Unfortunatly many years ago a fire destroyed the records. Also, many have been thrown out.
To those who are researching Benedict Arnolds reletives many are buried in my area including Peleg died 1835 at the age of 65 yrs and is buried in Orleans township.
