According to Lyon Memorial for the Connecticut and New Jersey branch (authored by members of the family, published in 1907), it is correct as Geni had it, unless I missed a recent change. (p. 89-90).
"ISAACS LYON [Thomas2, Henryi], was born in Newark, N. J. in 1691, and died Feb. 3, 1764; buried at Newark. He married Hannah, daughter of Rev. Abraham and Abigail (Clark) Pierson.
"The will of Isaac Lyon of Newark, Essex County, N. J., dated Nov. 17, 1763, mentions wife Hannah; children: Abigail, Jane, John, Eliphalet and Mattaniah; grand-child, Lucy Pierson. Items: wife Hannah received four large silver spoons; Abigail, teaspoons
marked E and £60; Jane £40. Executors: sons John, Eliphalet and Mattaniah. Witnesses: Elijah Bruen, Joseph Hayes, Jr., and Samuel Hayes. Probated Feb. 28, 1764"

The Lyon family was huge and resourceful enough to publish their own family genealogies, early on (over a century ago). Besides the Connecticut / NJ branch there was also a New York branch and a Massachusetts branch. All three branches are extensively recorded and documented, with substantial information provided in three books of genealogy written by members of the family working together on them.

I am related thru Mattaniah Lyon . I'm not really that knowledgeable about his siblings but I think maybe some extra kids got added that I did not know were extras. But according to the help and information you provided Private User that is what it looks like now. So again I thank you. :) I appreciate all the help I can get because I am still learning.
