Naming customs
The Pwr naming customs give each person an option of several names. Most commonly people take on two last names. The first last name is a patronymic which is derived from the father's name. Men use the prefix Nw- on the faher's name and lenite the first consonant or mutate the first vowel. e.g

Gŵésti Nwyddw (Gŵésti son of Éddw)

The second last name is derived from the grandfather's name where men use the prefix (written as a separate word in orthograph) Mwl  and lenite the first consonant or mutate the first cowel. E(

Gŵésti Nwyddw Mwl Ddarishw (Gŵésti son of Éddw, grandson of Darishw)

For women the first last name takes on the prefix Ni- but doesn't cause any lenition or mutation e.g

Féri Niéddw (Féri daughter of Éddo)

The second last name is derived from the grandfather's name where women use the prefix *Niri* e.g

Féri Niéddw Niri Darishw (Féri daughter of Éddw grandaughter of Darishw)

when a woman marries she drops her second last name and takes another based of her husband's first name with the prefix Sa- (meaning 'with') this causes no lenition or mutation e,g

Féri Niéddw Sawfofsdé  (Féri daughter of Éddw wife of Wfofsdé)
