Gulliema Elizabeth Lamb (Nixon) - too young to have a baby

It's coming back to the discussion - for Mary Nixon

We must have her birthdate wrong; her husband was born Jan 7, 1710 -- I think we have the wrong Piece Family and wrong Mary attached

or the marriage date and children that have been added over time-

Nixon names are common

What I did find was the original Friend's Meeting intention of marriage -

Please review they married 10 years later than we put on Geni.com
this is probably the root of the problem.

So, Elizabeth and Mary would be another wife's daughter's?

Now we have an original document I say, we put 1740 as the marriage date and all children born after as Mary Nixon (Pierce) children

Children born before we should put with mother unknown until we can find the original documentation of that marriage.

Those Children
are

Elizabeth Nixon born Dec 10, 1731/1732 Married Isaac Lamb

Mary Nixon born July 9, 1734, married Elliott Jones
Some of the above facts of the two children may be wrong I copied from the Nixon genealogy book.

The two daughter's are well documented as Dr Phineas Nixon's daughters = perhaps his first wife's name was Mary as well, who knows at this point, but the Metting notes prove this Mary Nison (Pierce) wasn't their mother, besides being too young between age 9 and age 12 -
