Y bore heddiw, gyda'r haul yn goleuo stoneau gwych Castell Caernarfon, Gwyneth cerddodd i mewn drwy'r porthdy mawr.

This morning, with the sun illuminating the brilliant stones of Castell Caernarfon, Gwyneth walked in through the large gatehouse.

Roedd hi'n dal yr ymyl cyffro ac ofn, fel pe bai ei stori am ddod ar draws ei llinell olaf.

She held the edge of excitement and fear, as if her story were approaching its final line.

Yno, yn yr ystafell fawr, clywodd crafu bach plant yn chwarae, sŵn seiren cymdeithasol y teuluoedd twristiaid.

There, in the great hall, she heard the little scuffles of children playing, the social siren sound of tourist families.

Ond roedd llais hen a chyfarwydd yn tynnu ei sylw.

But an old and familiar voice drew her attention.

"Eira, Caradoc," fe alwodd, ei lais yn ddigon uchel i dorri drwy'r dyrfa.

"Eira, Caradoc," she called, her voice loud enough to cut through the crowd.

"Bydd hyn yn wahanol," meddyliai Gwyneth.

"This will be different," Gwyneth thought.

Doedd hi ddim eisiau rhyw ailadroddiad traddodiadol lle roedd hi bob amser yn disgyn i'r cefn.

She didn't want a traditional repetition where she always ended up in the background.

Pan oedd y brodyr a chwiorydd wedi casglu gyda'i gilydd dan y porth, gwnaeth Gwyneth ymdrech.

When the brothers and sisters had gathered together under the gate, Gwyneth made an effort.

Roedd Eira yn edrych gyda'i wyneb tanbaid cyfarwydd, tra oedd Caradoc, gyda'i gonsentradau trwm, yn wir brawd hŷn.

Eira looked with her familiar fiery face, while Caradoc, with his heavy concentration, truly appeared the older brother.

"Rydw i wedi newid," dechreuodd Gwyneth, ei llais yn ffyrnig y tro hwn.

"I have changed," Gwyneth began, her voice fierce this time.

"Ac rydw i angen i chi wybod hynny.

"And I need you to know that."

"Roedd Eira a Caradoc yn edrych ar ei gilydd, chwilio am ymholiad yn wyneb ei gilydd.

Eira and Caradoc looked at each other, searching for inquiry in each other's face.

Ond yna, gyda gwen cynnil, symudodd Caradoc ymlaen yn gyntaf.

But then, with a subtle smile, Caradoc moved forward first.

“Dywed, Gwyneth.

"Speak, Gwyneth."

”Cerddasant i’r ramparts, lle roedd y morwedd yn hwylio’n isel ac roedd awel organigdeimlad yn siglo'r baneri.

They walked to the ramparts, where the sea was sailing low and a spirited breeze was swinging the flags.

Roedd Gwyneth yn aros, teimlai oherwydd bod popeth yn newid yn y moment hon.

Gwyneth paused, feeling that everything was changing in this moment.

Roedd y castell enfawr yn ei atgoffa o'u hanes fel teulu, craig o draddodiadau a dyheadau.

The massive castle reminded her of their family history, a rock of traditions and aspirations.

"Roeddwn i bob amser yn teimlo fel yr un mewn cysgod," dywedodd Gwyneth, ei llais yn tynnu o'r môr islaw.

"I always felt like the one in the shadows," Gwyneth said, her voice drawing from the sea below.

"Roedd yn teimlo fel pe bawn i byth yn ddigon dda.

"It felt like I was never good enough."

"Safodd Eira a Caradoc yn dawel i ddechrau, fel pe baen nhw'n rhyfeddu at agoriad eu chwaer fach.

Eira and Caradoc stood silent initially, as if they marveled at their little sister's openness.

Ond yna dechreuodd Eira siarad.

But then Eira began to speak.

"Rydym ni i gyd wedi newid," meddai'n feddwlon.

"We have all changed," she said thoughtfully.

"Efallai nad oeddem ni'n gweld hynny.

"Maybe we didn't see that.

Diolch i ti am ddweud.

Thank you for saying it."

"Caradoc, yn ddirybudd, ymunodd, "Ac mae hynny'n bwysig, Gwynnie.

Caradoc, unexpectedly, joined in, "And that's important, Gwynnie.

Tydi ry'n ni'n falch ohonot ti.

We are proud of you."

"Roedd Gwyneth yn ddiymgeledd, ond yn hapus.

Gwyneth was vulnerable, yet happy.

Roedd y pwysau wedi bod ar ei ddisgiau uchaf wedi symud.

The weight on her uppermost disks had shifted.

Roeddent wedi codi ei llais ar y ramparts hyn lle roedd y môr yn galw a’r morwedd yn cwffio am sylw.

They had raised her voice on these ramparts where the sea called and the seascape wrestled for attention.

Unwaith eto, roeddent yn angen aelod o'r teulu.

Once again, they were a family member in need.

Er mai arhosiad byr, teimlai Gwyneth olwyn gefnogaeth yn ffurfio'n ffrio yn ei hamgylchydwyr.

Though it was a brief stay, Gwyneth felt a wheel of support forming solidly in her surroundings.

Roedd Caernarfon, gyda'i ystafelloedd a'i hanes, wedi cadw ei wiri, ac roedd ei feddwl trwy hyn oll fel band ac amlwg i gyfanrwydd y teulu.

Caernarfon, with its rooms and history, had kept its promise, and her thoughts throughout it all were like a band, clear and obvious to the entire family.

Gyda’r nt awelon o’r môr, cerddasant allan o’r castell, gyda heartau gwell, gyda’r promise i bob amser fod yno am ei gilydd.

With the sea breezes, they walked out of the castle, with better hearts, with the promise to always be there for each other.

Roedd yr haul yn troi eu llwybr ymlaen yn olau, a gwnaeth Gwyneth sylweddoli bod ei deulu, am y tro cyntaf mewn amser hir, yn deall.

The sun turned their path ahead bright, and Gwyneth realized that her family, for the first time in a long time, understood.

Roedd y foment hon yn dyfodol newydd, un lle byddent gyd-fynd, fel cerrig sylfaen y castell oedd gyda'i gilydd yn canu cân gartref.

This moment was a new future, one where they would belong together, like the foundation stones of the castle singing a song of home together.
