What were the names of former alliance party leader Oliver Napier's parents?

There is a story in my husband's family that they are related to the former leader of the Northern Ireland Alliance Leader Sir Oliver Napier. Since I have been doing my husband's family tree just wondered if anyone knew the names of Oliver's parents to find out if there is any truth in the tale.|||http://en.wikipedia.org/wiki/Oliver_Napi鈥?/a>
