Eric - there is a presentment in Braddan dated 29 Jul 1759 that judging from my index mentions several young males as some referred to as 'junr' including Thos s/o Gilbt Kewley - seems associated with Thomas Watterson who appears to have kept a lewd house but I'm off Island for another week or so thus can't chk.

I noticed the discrepancy between dau Jane + dau Mary in the two wills but I did the summaries in days when photos were not allowed and I couldn't afford photocopies - possibly Peter might clarify the point he is hinting at if he has actual info; niece is often used to hide some illegitimacy
