the Dinwoody connection is discussed in an earlier posting in 2000 http://www.isle-of-man.com/cgi-bin/interests/genealogy/bulletin/index.pl?noframes;read=10232 which also links to south africa and USA emigrations

(it is this SDinwoody connection that accounts for the many patron submitted entries in IGI (many apparently erroneous/wishful thinking) - there was one query raised however the IGI has a female Olive baptised, one researcher thought it should have been a son Oliver (which was in fact one of the patron submitted entries) - the IGI doesn't usually get the gender wrong as PR entries are son/daughter of .. - however I've not looked at those PR's and I only used the entries supposedly from the 1911 transcript)

it may well be that there were several downward families in the Island at the same time, there doesn't appear to be any linkage and the naming patterns are different - my interest is in the brief appearance in Peel as some 50 years later there were still two properties possibly named after the family

Thomas, Charles and John are first noted late 18th C - possibly come-overs from northern Ireland ?
