The Centre for Irish latin American Studies has an interesting article concerning Susanna Beamish-Strachan http://www.irlandeses.org/imsla2011_7_04_10_Conrad_Hicks.htm

She was born outside Dunmanway, Co. Cork to a Church of Ireland family but formed an attachment to the Methodist Church.  She left to go to a Bible College in London and met Henry Strachan (1872-1945) a Canadian of Scots decent.  They went to Argentina, and over the years travelled as missionaries in South and Central America settling in Costa Rica.  They founded a Bible College and the article documents their work.
