A "cheeky, happy" teenager died after a quadbike accident in Zante during his first lads holiday.
Jack Howe, described as a "cheeky, loving, happy, kind, bestest friend and little brother", lost control of his quadbike on the party island last month.
Devastated family members said the 19-year-old and his pals were "advised not to wear helmets" after hiring out the bikes.
Now relatives have raised almost £10,000 in his memory, Kent Live says, and are helping other bereaved families repatriate lost loved ones.
Jack's devastated sister Hannah wrote on Facebook that the "end goal of this is to become a registered charity and make a difference to less fortunate families who can’t bring their loved ones home and raise awareness of how dangerous quad bikes can be".
The family's JustGiving page explains: "We were fortunate to be able to fund Jack's journey home as quickly and efficiently as possible.
"In some cases families are not lucky enough to bring their loved ones home, adding to further stress and devastation to the family.
"Therefore we have chosen to raise funds in loving memory of our brother Jack to support these families.
"Any donation and support will be very much appreciated in loving memory of our Jack.
She describes Jack as her "cheeky, loving, happy, kind, bestest friend and little brother," adding: "You have no idea how much we loved you and what an amazing brother you were, the best in the world actually.
"We had so many laughs, holidays, birthdays, memories, days and nights out, special times and of course our rowing matches. You brought our family so much joy and happiness and it’s such a shame you will never know how much you meant to us all.
"We don’t feel unlucky that you have been taken from us, we feel honoured that we were lucky enough to know and have you in our lives for 19 years."
His twin sister Lucy echoes this sentiment, posting on Facebook: "No one will ever have the connection we had, I was lucky enough to know you that nine months longer than everyone else.
"We will always be the five of us, you will never be forgotten, forever and always my angel. So many people loved you, I just wish you knew how many people's hearts you’ve touched.
"I can’t wait to see your face again one day. Come home one more time please. You’ll never be replaced geez. I hope I make you proud."
Jack's funeral will be held this Friday (July 12) at 11am at St Mary's Church in West Malling.
Attendees are asked to arrive at 10.30am and to be "as colourful as you want as that's what Jack would have loved".
