Basque <aran> `plum' resembles various words in both Romance and Celtic,
but no direction of borrowing seems to be phonologically plausible.
According to the standard etymological dictionaries, the Romance words
require *<agranio>, while the Celtic ones require *<agrinja> -- neither
of which looks like an obvious relative of Basque <aran>.

Could aran be from an original form *agran-?
btw: what are the other forms in Romance & Celtic?
Maybe Dennis "Donncha" King might have some insights on the Celtic forms
