Greenhalgh-Entwistle Family Connections

I am looking for anyone who might know about family connections between these two families.I am trying to find the ancestry of Samuel Entwistle.The information I have is from a marriage certificate on 28 Nov 1839 in Bury.On the certificate it indicates his father's name as Joseph Greenhalgh.His bride's name was Mary Ann Greenhalgh, daughter of James Greenhalgh of Tottingham.I am convinced that I am only going to be able to find Samuel's ancestry through the Greenhalgh line.Thank you.
