"The Papers of the Smith-Bromley Family" GB 19 SM (U-Nottingham) contained an addendum "Miss Howe's Case" SM1112. In the latter, it is stated that both James and Emanuel Howe died without issue. I kept up the search however; I was surprised to have found in the "Will of John How, Gentleman of Woodford (and of St. Bartholomew by the Exchange) (1747)" from the National Archives (Canterbury). Remarkably, in the first paragraph, he disinherits his eldest son, Joseph How, for excessive spending. His other sons John and Robert, witnessed the will, but Joseph did not. I have found the baptismal records of the the three sons - St. Bartholomew by the Exchange. Joseph was born 14 May, 1704. According to family lore in the States, our Joseph Howe immigrated to Boston imn 1747 - the same year that Joseph Howe was disinherited!
I believe have found the brother's will, John How, Gentleman of Romford 1775. In it, the brother Robert witnesses the will of his brother John, but not Joseph. The John How of Woodford, I believe is the son of John How, Gentleman of Somerset-Earnley, the grand-nephew of Sir George Howe, 2nd Baronet. I surmise that Robert How could also be the grandfather of Edward James Gambier Howe (Howes of Chart Place). I would very much like to obtain the pedigree of these Howes, to verify my hypotheses. I have requested the
"Papers of the Gambier Howe Family" from Kent County Archives, in hopes of finding mention of Joseph. Thank you.
