I saw your posting regarding Garrett Walling and Sarah Thorne, they are my 4x g-grandparents. Their daughter, Mary Amanda Walling married Burrit Anderson in 1829 in Monmouth County, New Jersey.
Together they had 11 children, three of which are buried in New Jersey, one for sure is buried in the same cemetery as Sarah (Thorne) Walling.
In 1830, 1840, and 1850, they lived in Monmouth County, New Jersey in the towns of Middleton, Keyport, Keanesburg, and Raritan Township.
In 1851, their youngest son Joseph died in Monmouth County. In 1852, Louisa, their oldest daughter married John Oterson, and moved to Manhattan, where she lived close to her uncle Thorn Walling.In 1853, their youngest daughter, Adelia died in Monmouth County.
By March 9, 1855, Burritt and Mary Amanda moved to New York with the remainder of their children and lived there the rest of their lives.
I have additional information and two pictures of Mary Amanda Walling Anderson with her family.
