Ichabod moved to Rochester, NH and his unnamed widow was buried there 14 Aug 1805 - known otherwise as Abigail Roberts. Ichabod's will was dated 22 Feb 1799 and proved 1 Nov 1801.
Lived on Salmon Falls Road, Rochestor, NH at one time (?). May be one list as public and civil service in Revolutionary War (DAR Patriot Index) as having had other wives: 1. Mary Allen, 2. Joanna Twombly. May be same as listed in NEHGR Vol 22 page 117 as being in Capt. Peter Staple's CO. in expedition against Louisburg in 1745. On same listing in Vol 25, page 250, shows also an Ichabod Cousins in the same expedition.
