Hello Private User.
I'm responsible for a lot of the Overviews and information about the Johnson family. My grandmother was Hazel Adele Johnson.
I have moved and can't put my hands on my primary source which is a very well researched book by Gareth Johnson https://www.amazon.com/Biography-Genealogy-Captain-Johnson-Massachu...
Find a Grave is NOT a reliable source for our Colonial ancestors in general, although occasionally you find a Find A Grave contributor who is a good researcher and strike gold. I doubt very much that I cited Find A Grave for Mary Heath Johnson.
Instead, I believe a lot of my material was from the Gareth Johnson biography.
I see that the biography is on the floor of my new office, waiting to be put away. I'll take a look at it.
Your point about citing sources is totally correct. When I first worked on Geni, I did not always cite sources, but have learned my lesson.
If we can't find a reliable source for the marriage date, I will remove it.
She is my 9th great grandmother --
