Catherine and Ben Mullany were shot during their honeymoon
The families of a couple murdered on their Caribbean honeymoon have launched a memorial fund to help medical students follow in their footsteps.
The Mullany Fund will raise money to support UK students wishing to study medicine or physiotherapy.
Catherine and Ben Mullany, both 31 and from Pontardawe, Swansea Valley, were shot in July at a hotel in Antigua.
Ben's brother Adam said: "The fund will help us to preserve their memories and ensure that their dreams live on."
The couple travelled to the Caribbean island following their wedding at St John the Evangelist Church in Cilybebyll.
They were shot on the final day of their two-week honeymoon.
Speaking on behalf of the families, Adam Mullany added: "Cath and Ben dreamt of a married life caring for others in the local community - Cath as a doctor and Ben as a physiotherapist.
"Cath and Ben's dreams were cut short by their murder on the last day of their honeymoon.
"The Mullany Fund has been launched by the family and friends of Cath and Ben to support UK students wishing to study medicine or physiotherapy.
A logo has been created for the fund which also has a website
"As a family, we have lost two beloved members. The Mullany Fund will help us to preserve their memories and ensure that their dreams live on.
"As a country, we have lost a well respected doctor and a promising young physiotherapist.
"Whilst we will never replace Cath and Ben, this fund will help others to fill their shoes and continue the work that they had started."
A website has also been launched which gives instructions on how to donate and has a guestbook facility for visitors to leave messages of support.
A range of fundraising activities are being drawn up.
A memorial service is being held at Llandaff Cathedral in Cardiff on Wednesday, 10 September to give family, friends and colleagues an opportunity to pay their respects.
Speaking about his brother, Mr Mullany said: "Ben was training to become a physiotherapist. No matter what work he did, it was always something that involved helping people.
"Ben served his country in the army and he was a police officer. He just wanted to help.
"His life outside of work was always full of laughter and he never lived at less than one hundred miles per hour.
"Cath was the love of Ben's life and he would pick nothing over spending time with her, but his love for rugby was well renowned and he would always make quality time for his friends and family.
"Ben's values and optimistic outlook on life will carry on through everyone he ever met and he will be missed forever."
Catherine's family added: "Cath enjoyed an idyllic childhood on the family farm. She decided at a very young age that she wanted to be a doctor.
"Her childhood dream became a reality when she graduated from London's Imperial College in 2002, shortly after doing a six week course in Adelaide.
"During her training and after graduation, Cath worked in many London hospitals and others around the country before returning to South Wales.
"Wherever she went, she was noted as being a caring, confident, conscientious and popular team worker. Her enthusiasm, love of life, sense of fun, broad smile and infectious laugh touched many lives.
"Cath and Ben met just over three years ago and it soon became obvious that they were made for each other.
"They were blissfully happy together and full of plans for the future."
A man and a youth have been remanded in custody charged with both murders.
