the wm cain margt + goldsmith entry needs checking against the actual register (I didn't personally check post 1800 births) as I suspect it may be a transcription error tho on first sight does look an unusual error to make - there is no marriage for this pair but there is a wm kelly + margt goldsmith (living at ballachrink Michael in 1841) & she would fit well into this family - in 1851 birth par given as onchan but then rest of family's birth parish entries are wrong
