I have to say this is the first time "special" has ever shown up in my research and I'm quite intrigued....so here is some info that probably fits your Abigail.Unfortunately, I had not learned to properly document proof in the early stages of my research so I can't tell where the info came from. Abigail Scudder Udall B. 29 May 1822 probably on Staten Island M. William Henry Mott on 25 Jan.1843 D. date and place Unknown Her parents were: Philip Udall B.Nov. 1792 Northport D.21 Jan. 1836 M.Hetty Scudder on 27 Apr.1819 in Flushing B. 4 May 1793 D. date and place unknown Abigail may have had sisters: Elizabeth and Phoebe Ann.
Philip's parents were Nathaniel & Elizabeth Ackerly Udall of Northport/Centerport. Philip was brother to my GGgrandfather,Jonas,of Northport/Centerport/Babylon.
Maybe this will connect to your research...I hope so..let me know if it fits.
