“No words can truly capture what a special person she was, her dedication to her work at Liberty of London reflected her hardworking nature, but above all, she was the cornerstone of our family.
“She was taken from us far too soon, and her sudden passing is a heartbreaking loss.
“She leaves behind a cherished husband, loving siblings, and adoring nieces and nephews who will forever hold her in their hearts and will live with the pain of not having her here with us forever.”
