On 19 January 1683/4, Margaret Howland included her heirs in her will as follows:
Her grandson: John Walker
Her son: Arthur Howland
Her grandsons: Ebenezer Howland, Thomas Howland, Arthur Howland
Only Arthur Howland is confirmed to be her son in her will.
Why not should Arthur Howland, Sr.'s daughters and grandchildren included in her will?
We know that her son, John Walker predeceased Margaret in 1663. Also, we know that Deborah (Howland) Smith and Elizabeth (Howland) Low predeceased Margaret in 1664 and 1678 respectively, but Mary (Howland) (Williamson) Stanford and Martha (Howland) (Damon) Bacon survived her in 1684.
On 25 January 1683/4, Her inventory showed many things in her house, and she wrote "I give and bequeath all the Rest of my estate both Reall and personall Moveable and Immoveable to my son Arthur howland and to his heires and Assignes for ever."
Why not some of her things could be given to Mary, Martha or any of her husband, Arthur Howland, Sr.'s other grandchildren?
How difference are Arthur Howland's will and her will in regards to their heirs?
Perhaps, if any matrilineal descendants take the mtDNA testing, it may hold answers in regards to that question.
