I have located the baptism of Michael Pillion son of Jacobi & Maria Pillion - the records are recorded in Latin and the names need to be translated.The baptism is listed on March 23, 1841 in Athlone, Ireland.
Also the death or funeral of Thomas Pillion on January 11, 1836.It listed some reference to Castletown.
Also, Guillielmus Pillion (again the name needs translation) was a sponsor in baptism for a female child with the last name of Collins. The date was November 25, 1721 Athlone, Ireland.
The info is from a microfilm of church records in Athlone Ireland that is at our local Mormon Church library.
