Cahalan, Cahalens or Cahalen

My Ancestor, James Cahalens(sic) was married in 1761 in Salem, N.J. under the King's Bond to Rachel Howel (sic). This is where it dead-ends back to Ireland. I have DNA online at Ancsstry.com. If anyone has a match, please contact me. Thank you. Don Cahala (Cahala-Cahaley on my ancestors tree)
