Sisk Surname In Antrim?

My surname is Sisk and I have traced my family line to a John Sisk born about 1706 in Co. Antrim. His son also a John Sisk b abt 1737 is also listed as born in Antrim in some records and U.S. in others. But thats not really important, my question- is anyone aware of any Sisks from County Antrim. Everyone in my family has always said that we were from Cork. Thats a bit off!
