Hector Maclean OR Mclean B Abt 1857 Cape Breton

This is my Great Grandfather I have found his marriage 1885 to Elizabeth Mcphee (PEI). I also have his death records in Boston. He names his parents as Daniel McLean and Mother as Mary McNeil on his marriage license. I have found lots of Hectors but none with those parents names. He married Elizabeth McPhee from Prince Edward Island I have her info but am really hoping to find his birth, thank you in advance for your help. I am looking to make a trip to Cape Breton in July and would really like to find his homestead. Thank you in advance for any help.
