My great Grandmother was Lavery and she was born 1871 in the townland of Rathmullan. Since doing research I have found that Lavery and O Laverty are two different families in the area. Sometimes the "O" can be missing and it can be spelt Lavery/Laverty.
Do you have the name of John Joseph O Lavertys wife. Also , do you know when he arrived in Southampton.
