Here we go again

Mary Ann Mylrea B Abt 1854 K/M daughter of John Mylrea B Abt 1819 K/M & Margaret (Brew??)B Abt 1815-1821 Douglas

Mary Ann married John Corkhill Waterson Cowley 6/10/1891

John Mylrea's Sister Mary Married William Mylrea
their daughter Francis married Joseph Kaighin 13/2/1904 died 16/01/1904

Joseph's Mother was Margaret Christory
I would like to know who Joseph's Father was
1901 wales census he is living with Aunt Jane and Mother Margaret

on the 1861 census there is a susan corlett age 22 the IGI shows a susan christory mother Christory I would like to know who the father was

and finally on the Mylrea side in 1881 census there is a john H Corlett grandson but i can't find any trace of his parents

I hope this makes more sense this time
