Tributes to Luke Wheaton
Taken from us way too soon. Words cannot describe what we are going through.
We are so proud of Luke who is the most gorgeous, loving, happy, talented, perfect son. Luke had everything to look forward to in life and has left a massive hole that will never be filled.
Luke is going to be missed by so many, first and foremost his family who he adored (including Harvey) and his huge network of friends including football, rugby and school.
Luke knows how much he is loved and will be dearly missed by everyone. We just wish we could bring him back. Always in our hearts and thoughts – life will never be the same again.

Tributes to Ray White
The whole family are struggling to come to terms with Ray’s death.
He was a wonderful son, brother and father to his two sons. He will be deeply missed by all who knew him.
Tributes to Brian Vickery
There are not enough words to describe the impact Brian had on not only his family and closest friends but to so many others.
He brightened everyone’s lives with his cheeky and wicked sense of humour.
Nothing meant more to him than being around the ones he loved and it’s difficult to think of him without it bringing a smile to your face.
We feel blessed to have had him in our lives and we will cherish these memories forever.

Mike was a brother, husband, father and Grampy. He will be missed.
