William Gullett came to Somerset Co. MD in 1671 m. Susannah Mills 1674 five children are recorded in church records but there may have been others not in church records.

Mary b. 25 Oct 1675
Susanna b. 30 Jun 1680
Grace b. 03 Mar 1682 Twin

Others have said there were two other sons John and George. John being the one in Cecil Co. MD by 1704 I have no proof of that.
William b. ca 1648/53?
Susannah ca 1653/56?assuming she was between 18-21 when married.
William d. ca 1687 according to some. Susannah ca 1714/17
Most of the early Gulletts I have found are listed in Devon England. I have posted 2 page of them as Gulletts Born Before 1700 England on this site. The earlist I found was named Robti Gullett b. before 1583. William does not match any of those on these lists.
Gullatt is a variant of the Gullett surname. I descend from John and Sarah (Last Name Ukn) Gullett of Cecil Co. MD John b. ca 1685 m. ca 1709. Earlist record of John is a 1704 court document suing for his freedom from and indenture he had completed. Spelling was changed in settlment of his his son John Gullett/Gullatt's estate 1753-1755 by court clerk.
All the early Gulletts in America had English given names so it is thought that they came from France to England ca 1540 to 1575 giving enough generations for the change from French to English given names. They likely were French Huguenots (followers of John Calvin) who fled France, the Huguenots were servely persecuted after about 1540 with thousand slain on St. Bartholemew's day 1552.
It may also be that some fled to Scotland or Ireland or the Netherlands, Germany or the Swiss Cantons with different spellings of the surname according to which country they fled to. No one knows for sure it is all guess work.
Susannah Mills was an indentured servant to David Browne and came on the same ship as he. He was called a Scots rogue so she may also be of Scots descent.
You can go to Maryland Archives and read many early court documents on William and Susannah. Seach for the names gullett, gullet, gulick, gulnick.
It was mostly the Gilletts who came to New England.
