Ex-voto. An ex-voto is a votive offering to a saint or to a divinity. It is given in fulfillment of a vow or in gratitude or devotion. Ex-votos are placed in a church or chapel where the worshiper seeks grace or wishes to give thanks.
Ex rel. is an abbreviation of the Latin phrase  ex relatione  (meaning [arising] out of the narration [of the relator]). The term is a legal phrase most commonly used when a government brings a cause of action upon the request of a private party who has some interest in the matter. The private party is called the relator in such a case.
