I've tried to copy the page for Elizabeth Eleanor Moore's father, William Moore b 1824 Arbory, showing his parents (of course, it all needs checking) and his second wife, Catherine (nee Sayle?) b 1835 plus their children, and then his first wife, Margaret Kelly 1828-1849 plus their children.
To save you wasting any of your Ancestry credits on "wrong pages", for 1841 IOM type in William Moore b 1823 in parish of Arbory ---- there's only one person who fits these details.
For 1851 type in William Moore b 1823, living in Castletown, born in Arbory. This shows William Moore son in law, widower 28 gardener b Arbory, with Mary Kelly, head wid, age 50 b Malew --- also Mary A niece 5 and Margaret niece 3, both b Castletown. The "niece" relationship doesn't fit with the 1861 entry in which these 2 "nieces" become daughters of William. I suspect that they should have been "granddaughters" in 1851.
These extracted baptisms from the IGI to parents William Moore and Margt:
3. MARGT JANE MOORE - International Genealogical Index
Gender: Female Christening: 29 MAR 1848 Saint Marys, Castletown, Isle Of Man, England
4. MARIANNE MOORE - International Genealogical Index
Gender: Female Christening: 14 SEP 1845 Saint Marys, Castletown, Isle Of Man, England
************************************************
For 1861 type in Wm Moore b 1823, living in Castletown, born in Arbory. Elizabeth Eleanor shows up as a 1yr old (Elizth Ellinor), and Wm is now married to Cath who is probably nee Sayle (my guess)
For 1871 type in William Moore b 1824 living in Castletown, born in Arbory.
I'll try and post this message with the copied details below. If it comes out all scrambled up, I'll type it out manually later.
