A few reasons I think the Stark line as it is currently on WikiTree is very suspect.
James Stark who emigrated to Virginia has a note to say there is no evidence for his parents though he has parents on WikiTree. He has a half-brother John Starke V who was born in Viriginia but there are no sources that I can see for his parents or that confirms they are brothers.
Elizabeth Thornton seems to be married to both James Stark and his father John Stark IV
The father John Stark IV has a note to say he was born in 1665 at Glasgow and in the bio the date 18 Jun 1665, but searching Scotlands People the John Stark, born or baptised 18 June 1665 at Glasgow was the son of Gilbert Stark and Agnes Williamsoun (presumably Williamson)
Although perhaps not all records are on that website, I couldn't confirm any of the details at all that relate to the Scottish line of Starks as currently on WikiTree and I would really recommend that they all need to be investigated and appropriate sources found.
