Here is a translation:
They produced four sons and as many daughters
The two girls they held close to their breast in their hours (the next word is cut off)
The other six children traveled to the foreign lands.
They worked hard. They lived happily
But,. one daughter died as she became a mother of a daughter
And... after she died one of their sons.
Three sons, one daughter were in America
She became a mother of two sons, but she died as well.
The mother could not take this third blow.
The next year in her village the church bell sadly tolled
She flew to find the beautiful Fyllia
And her other two children, Stavros and Maria
With this plaque the children cover the parents
Their son Panagiotis with a heavy heart
And these verses were written by their nephew Evagelos
A token of gratitude to mother Kalomoira
and filial love to Triantafyllia
Because she suckled them together when they were infants
