Jicks/Gicks were not that common in Braddan/Douglas (it is a Santan/Malew name) - my suspicion from 1851c is that Wm was s/o John Gick & Mary Kelly (m Braddan 17931228) and bur Braddan 18281021 age 73 which would fit John s/o Wm Jick + Cath Christian (m Malew 17550617) bapt Malew 17580730.

Jane's age + birth as in 1851c suggests d/o Robt Crinnel + Jane Callow Lezayre bapt 17990302 (m Lez 17990525)
