Unfortunately the information you gave me does not connect. At least not at this point. Your Rev John Harley, born May 27, 1837, is not the same. The Rev John Harley and family I am looking for was born in 1728, on Harley St. If I have the right Rev John Harley, his son also John MD came to Nova Scotia and married a woman named Mary. One child was Benjamin Harley also a doctor.
If any of this is a connection to you or anyone else please let me know.
