Name Changes (General)

Was looking into family members and turns out one of my great great grandmothers was a housekeeper. During her time as a housekeeper she had my great grandfather, he was born a Weale and during his time living in the household he changed his name to Morgan, the same surname as the head of house. Also his brother Emlyn had the same happen to him, he was born a Weale and changed his name to Barnes another boss to his mother. would anyone have any idea why this was? of if it was common place?

thanks for any help anyone can give
