Hezekiah was born 1741, but I have his birthplace as Weymouth. You are correct about his mother and father. Grandfather was Samuel King, GG father Hezekiah King, GGG John King and GGGG John. GGGG mother was Mary King nee Blucks
John came to Weymouth in the early 1600.
Hezekiah came to Canada sometime around 1760-70.
Hope this has been some help. If you have any questions let me know and I>ll go through my files.
