Josiah's death date comes from the old Norfolk County death register 1870-1896 at the Chesapeake Courthouse. Those records were abstracted and published by Emily L. Walker. On page 246 of her book she lists the entry as being on page 5 line 151 of the register - Josiah Stewart, white, male, died 6 Jan 1892 in Providence Norfolk County of pneumonia at age 77 years. The son of Jos. & Mary Stewart, born in Great Bridge, occupation a laborer, unmarried (he was a widower) with the person giving the information being Jos. Stewart, his son.
Ashwell and Cordelia married in Camden County 10 Dec 1871 and her mother was simply listed as E. Overton. The Overton's lived very near the Whitehurst families in Camden County. Arthur was living in Pasquotank County in the 1850 census with his wife and child but I haven't found a marriage in either Camden or Pasquotank for the first marriage.
