As nobody had replied to this and as her husband was mentioned by Clive Burlton in his talk with reference to WW1 - I thought I'd better supply the answer.
On our own transcripts online you can find that on 31st Dec 1872 Anna Maria HARDWICK, the daughter of Dr John HARDWICK married Frederick Edward WEATHERLY, gentleman, son of Dr Frederick WEATHERLY.
Frederick Edward WEATHERLY was born in Portishead in 1848 and became a Barrister but is much more popularly known for his poetry and for the words for songs which he wrote including the words for Danny Boy which inspired my original question with its links to Ireland.
Amongst his approximately 1500 songs, Fred WEATHERLY also wrote the words for Roses of Picardy, Up from Somerset, The Old Brigade (which is played every year on Remembrance Sunday in the Albert Hall when the Chelsea Pensioners enter) and the song that Clive Burlton played during his talk - "Bravo Bristol!" written to rally troops to enlist in the 12th Battalion Gloucestershire Regiment, which became known as Bristol's Own.
