my suggestion was:
Thos Moore(Ballakilley, Onchan) married Cath Kelly m lonan 17661109 (? 2nd marr for Thos) - 4th child Jane Moore bapt Lonan 17740828 m Thomas Cannell Lonan 17951124
their 3rd child Thomas m Ruth Crellin German 18310424
Ruth buried Onchan 18420407 age 39 - she was d/o John Crellin + Cath Quilliam who m German 17920513 - John was I think bur German 18490922 age 79 and was possibly bapt Ger 17400725 s/o Pat Crellin + Alice Cottier (her will 1783)
