i'm new on here & this is my first post, so please be gentle

mine is a very long story but i will try to keep this short ... my family going back many many generations has lived in st davids (though i never have - only visited for hols etc) ...
last summer my grandad and aunt (william & gloria griffiths) passed away on the same day ... they had lived in nun street for over 50 years ...
my auntie gloria was very reclusive but in the 1970's had a book of her poems published ...
my dad has very little of his father and sisters memories / belongings etc, but is desperate to get hold of a copy of the poems, so i am trawling everywhere i possibly can to try and find it for him...
it is called '20th century poems' by Rose Petal, and i think was published in 1976...
do any of you guys know how / where i can continue my search???
i would be soooo grateful for any help as it really does have huge meaning in the family ...
i still have an auntie living in st davids, and my uncle lives in treledydd fawr, so still feel strong connection to the place myself, and its good to see a thriving little online community from there!!!
ps : even if i can only find the books isbn number it would be a help... or if any of you remember the family in st davids, it would be good to hear memories...
thank you for your time
