Found the correct parish records and uncovered the following:

1. JOHN1 LEWIN. He married CHRISTIAN TEAR December 2, 1800 in Kirk Michael, IOM.

Children of JOHN LEWIN and CHRISTIAN TEAR are:

i. ALICE2 LEWIN, b. October 21, 1801, St Matthews, Douglas, IOM (Source: IGI - LDS Webpage, C038041.).

2. ii. JOHN LEWIN, b. January 12, 1803, Douglas, Saint Matthews, IOM; d. December 26, 1838, Braddan, IOM.

iii. ELIZABETH LEWIN, b. August 7, 1806, St Matthews, Douglas, IOM (Source: IGI - LDS Webpage, C038041.).

iv. CHRISTIAN LEWIN (Source: IGI - LDS Webpage, C038041.), b. October 9, 1808, St Matthews, Douglas, IOM.

Maybe this will allow a few more connections...
