The family records I have indicate that the William Shimmin who married Catherine Callow on May 9, 1818 was chr. on March 14, 1790 at Kirk Malew and deid on March 27, 1863(buried at Balladoole). My records indicate he was the son of Edward Shimmin (ch. March 31, 1752 at Malew) and Margaret Cannell (married Feb. 24, 1788 at Kirk Michael).

According to my records this William Shimmin was the Father of Thomas and grandfather of Robert Henry.

I have no records earlier than Edward Shimmin married to Margaret Cannell.
