Not quite sure but
"A child of Isac Peat buried on Cae' mynydd and buried at the side of David Francis Llyfriniog .............**( under a year old - "dan flwyd"?)
** other entries on the same page attempt to identify the location of the grave - in this case
"Careg fed Argoed"
Single "d" used instead of double "dd" eg gladdwyd not gladwyd, fedd not fed, flwydd not flwyd -
Hope this helps
