Re: Karel Whyte's book
I have a 1999 edition of Karel's book, and for the third generation of Gerret, Thomas she lists these children:
Thomas b. 1708;Mary b. 1710;Lurannah/Laurana b. 1713; and
Van b. 1719.
She also has the will of Thomas, son of Gerret, which lists the four children above, but no mention of Linnias.
I also looked in the alphabetical index, and found no Linnias, or Thomas Moseley.
If you have any dates of birth or death, it would help trace with possible alternate spellings.
