Hi - The IGI has an extracted record (copied from the parish register) of his bapt as John GREAMS Christening: 01 JAN 1828 Malew, Father: WILLIAM GREAMS Mother: ELINOR CLAGUE.

William is recorded as Graham at his marriage 12 AUG 1827 Malew, as you say. If you want to see whether any additional details were given at their marriage or at John's bapt, the LDS film number is 0106732.

When Frances Coakley gets back from holiday she will probably be able to help you with your history query. In the meantime, have you looked at her website at http://www.isle-of-man.com/manxnotebook ?
