Hi Clive,
According to Tom Corteen's transcript from the original Maughold register volumes the entry recorded that Simon the illegitimate son of Daniel Callow and Issabell Kendry was bapt. 31 Oct 1736 [so no surname given for Simon at bapt].
There was an Isabell dau of John Kelwey bapt 1 May 1720.
Also Isabell dau of Patrick Kewley bapt 18 Oct 1713.
Several Kenish, etc., but no Kendry. Kewley seemed the most likely.
