I've come across a number of Espin bits and pieces as the surname is in my direct line. It's early days in the research though some of the names posted are common to my lot so maybe a connection somewhere.
William Espin abt 1740 (died Sep 1814, Barlings), is as far back as I have got, descendants around 1800-1830 around Barlings and then some around Barton, Grimsby and Lincoln.
Just in case it's any use, William, spouse and children
