What is more interesting is how Catherine came to be living in Castlereagh, County Roscommon, Ireland when all of the other Masterson matches that her great-grandson shares DNA with all come from Achill Island, County Mayo, Ireland.
Catherine was a servant. She may have gone there for work.
My Mayo grandma was a servant, 20 years before Catherine. She worked in Belfast and in 2 counties in England, returning to her father's home at various times, before and after marriage, depending on job prospects and family situations.
Employment opportunities were limited except in cities and large towns. Irish people were accustomed to leaving home for work.
Catherine didn't state her age at marriage. "Full age" is 21 or over.
