Hi
Miss Winifred Evans's obituary appears in Yr Herald Cymraeg 25/01/1960.
According to this she was former headmistres of Ysgol y Babanod (Infants School), Penygroes. Report says she died, 'Friday before last', and was buried at Macpela Cemetery, Penygroes.
There is a list of mourners, giving their family relationship, if any, to the deceased. I don't know if you already have this information. If not, I'll send it to you by PM as some of the younger mourners might still be alive.
I'll make enquiries at Gwynedd Archives re possible source of further info re Winifred.
Nearly forgot (!), at time of death she lived at Penhegan (in print so no deciphering problem); will try and find out where the house is/was.
