Neighbours of the family tragically killed in a plane crash at the weekend have paid tribute.
Sandhya Santsbachalli, 35, of Shenley Church End said she remembered Mrs Hewitt’s “smiling face.”
She said: “We’ve been here for two years and we met a few times.
“They came here to exchange Christmas cards and we went for Christmas drinks.
“I can just remember Fiona’s smiling face.
“They were a very close knit family, lovely children.
“It’s very shocking, very sad, may they rest in peace.”
Richard Hewitt, 50, Fiona Hewitt, 52, Felicity, 17, and Harry, 14, died instantly during a 20-minute sightseeing trip on the last day of their holiday.
The seaplane crashed in the Les Bergeronnes area of Quebec province, killing the pilot and another passenger.
Another neighbour said: “It’s tragic, they were such a nice family, they were so down to earth.
“They lived here before we moved in and we exchanged Christmas cards every year.”
Mrs Hewitt was a therapist and Dr Peter Berkin, who runs Alternatives with his wife, said: “She was just a lovely, lovely lady who was a natural healer.
“She had been treating people with us for 15 years. She was our longest serving therapist. She was with us right from the beginning.
“She was very popular with clients.
“They were a lovely family with young children. We have seen her children be born and grow up.”
