XII Renfrewshire (12th) Province
Neilston CC is affiliated to the RCCC (also known as Scottish Curling). Each club is a member of a Province and each Province is part of an Area. In the case of Neilston the Province is XII Renfrewshire (12th) Province, and the Area is Inverclyde (also comprising Argyll Province). The reason for the roman numerals predates the area structure when there were only provinces denoted by roman numerals.
