I can confirm what Tom Corteen said. Catherine, William and your great-great grandfather Daniel Christian were from Baldromma, Maughold. The next to be born was Isabella, who married Robert Kerruish, Ballafayle, and these two were the grandparents of our Patron, Sir Charles Kerruish.
Their mother was Isabella Kermeen, and her mother was Margaret Joughin, as he says. She was from Rhenabb, Maughold, and was an elder sister of my great-great-great-grandmother Alice (Ely) Joughin. By my reckoning that makes me a fifth cousin of your father.
I checked the dates you gave against the IGI and found that they matched the dates of baptism at Maughold, except that the IGI gives 24th March 1824 for Catherine. I wonder if the LDS made a mistake and wrote the number of the year instead of the day of the month. in the entry for your great-grandfather's baptism at Ramsey the mother's name on the IGI is Christian, though whether this was her forename or maiden name, as well as her married name, is not clear.
