James Fea I of Clestrain married Margaret Groat, who was probably a daughter of Malcolm Groat of Tankerness. While the date of their marriage is not known, it was certainly not more than ten years prior to the granting of the feu of Clestrain. They had, at least, four sons:
- John Fea
- Marie Fea. It is known that her uncle, Robert Fea, bequeathed 100 merks to be paid to her on her marriage.
An instrument of Sasine in the National Archives of Scotland makes reference to Olaw Fea in 1593

- Magnus Fea, who married Marie Groat and
- Robert Fea
There is a record of a Barbara Fea who married an Edward Scollay and she may have been a daughter. There is also a reference to an Ursilla Fea, alive in 1623, who may have been another although there is no evidence to support this.
James Fea I of Clestrain died between July 1629 and 28th April 1630, when
his testament was recorded.
