Thank you, Sue, for this most useful file. Some points.
Your first family lived at Baldromma (Mooar), just past Maughold Parish Church on the left hand side as you come from Ramsey. The fields stretch out to the Head. Your second family lived at Ballaterson, on the right hand side as you come down towards the Church. The families farmed their respective farms from at least the 17th to the 20th centuries.
The John Thomas Christian aged 14 months, Balterson, buried 29 Jan 1961 is tricky. His age fits him exactly to be the Baldromma infant. It could be that he died at Ballaterson, being looked after by his mother’s people. Constance Radcliffe makes him a child (1860-1861) of Edward and Jane Christian, Ballaterson, Edward being the one whose 1820 baptism you give in your second family. Do you find a baptism in 1860 of John Thomas, son of Edward Christian and Jane Quayle? CR has no John Thomas in the Baldromma family.
1971 Census, Maughold. For Ballamona (is there such a farm in Maughold?) I read Baldromma.
The next place, Ballacarna, is unfamiliar. Is it in Maughold? Could it be Ballaberna?
Robert Edward Christian 74 of Douglas olim Baldroma. Olim = once [upon a time] i.e. formerly.
The Monumental Inscriptions look to be taken from the IoMFHS book of transcripts.
No. 27. The Manx word in the middle should be GHRAYSE, meaning grace. The passage reads “And he said unto me, My grace is sufficient for thee”.
No. 24. …Dorothy Christian late of Ballure…Although this grave is next to the Baldromma ones, the Ballure Christians are another line again, up by the tram crossing over the main road out of Ramsey. Edward, in grave 23, was her brother.
In grave 25 Jane Elizabeth Christian, Baldromma, was a Christian, Ballaterson, niece of her mother in law Mary Ann, making the couple first cousins. Their son, Howard A. E. Christian, was the last Christian in Baldromma. When he died unmarried in 1971, he was still courting his first cousin, Mrs. Radcliffe told me, though whether she said who that was I don’t recall.
