William's estate was probated on October 1, 1661, in Middlesex County, Massachusetts and an inventory filed there on April 1, 1662. His estate was also probated at New Haven, an inventory dated March 3, 1662/3 appearing in the New Haven Colony Records. At the time the inventory was presented to the Court at New Haven the record states that there was to be present at the next hearing "the widdow with him yet she was to marry". "NOTE": At this time Ellen was planning on marrying a John Rose.
When William Luddington died at New Haven, although his residence there must have been short, he owned a house and land and also another piece of one hundred acres. Luddington's real estate was on the river that divides East Haven from Branford, where there were iron works established in 1655.
William died in 1661 at New Haven, Connecticut.
The information on the marriage of William and Ellen comes from the book "Memoirs of Colonel Henry Ludington" by Willis Fletcher Johnson
