Born in Auckland of Irish and Philippine parents, Shimna got her taste for Celtic music from her Irish side, and her singing voice from her Philippine side.

Showing musical talent at an early age, she started with Suzuki method, piano and violin, before being 'spotted' by local Irish Fiddle Legend Jono Lonie, who introduced her to the intricacies of the Irish Fiddle when she was 10, and taught her for the next 5 years.

She honed her skills by joining in Traditional Music Sessions held in Irish Pubs around Auckland, notably The Bog in Parnell (now sadly closed), Florrie McGreal's in Takapuna, The Claddagh in Newmarket and The Clare Inn on Dominion Road, where she's still to be found most Monday evenings.

Shimna's performance talents were nurtured by the local Folk Music scene, where she took her first steps in playing and singing for an audience. She grew up attending the annual Auckland Folk Festival, held at Kumeu Showgrounds in late summer, and has played there and in the local folk clubs: Titirangi Folk Club, Rafters Folk Club (Ponsonby), and at The Bunker, Devonport

She also had a couple of tastes of the real thing, at the Joe Mooney Summer School in Drumshanbo, County Leitrim, Ireland in 2011, and at Scoil Eigse at the All Ireland Fleadh in Derry, August 2013

Shimna was the first New Zealander to compete in an All Ireland Fleadh (under-15 fiddle, Derry, 2013)

After the Fleadh she stopped off at the Cliffs of Moher to shoot this video

Back in NZ, Shimna was the winner of the Scottish Fiddle Championship held at the Highland Games, Waipu, January 2015.

2015 turned out to be a big year for her music, as she also received the Frank Winter Award, and the Martin Blackman Award, at the Auckland Folk Festival, January 2015

The Martin Blackman Award included studio time sponsored by Heron Studios, Kumeu, and this has resulted in her debut 4-track EP CD "Whitmarsh" (released January 2016).

She appeared on TVNZ on St Patricks Day (17 March 2015) as part of "The Father Ted's Band" (thanks to Celtic Musician Gerry O'Neil for the invitation), and on a float in the Auckland St Patricks Parade as a member of the band "Fable"

Shimna has peformed solo for a Tourism Ireland function, for weddings (solo and as a band member), and has performed as backing musician on the X-Factor and Dancing With The Stars TV shows
