I think the query is that Jane is shown alone with just one dau at Baldroma in 1841c but there is a burial for a thomas age 45 a few days prior to the census which would have confirmed Thomas's age (the marriage was just a little after my stopping point for looking at Lonan marriages so I never transcribed that one) - age 15 at marriage would certainly require some note in the reg - he may be the son of John + mary Quill but looks as if inheritance of farm was a key query as 1st child was bapt 9 months later (that too surprises me for a 15 year old (only just 15) given age of puberty was generally consider later
