The family of a mother and her young son killed in their home said they would be "sadly missed".
Suzanne Jones, 34, and her two-year-old son William were found dead at their home in Glanmorfa Terrace, Porthmadog, Gwynned, on Friday night.
Mrs Jones's husband - and William's father - David Wyn Jones, 42, has been charged with their murders, police said today.
Neighbours said the couple also have two daughters, Antonia and Amy.
Mrs Jones's mother Eileen Holt said in a statement released by police: "We will all miss Sue and Wil so much.
"Sue was a fantastic mum and daughter and Wil was a lovely little boy who will be sadly missed by us and his sisters.
"We are now concentrating on looking after our granddaughters and ask that our privacy is respected."
David Jones will remain in custody before appearing at Caernarfon Crown Court tomorrow.
North Wales Police were called to the address in Glanmorfa Terrace at 9.20pm on Friday and the pair were declared dead at the scene.
Detective Chief Superintendent Neill Anderson said today: "Our thoughts and deepest sympathies are with the family and friends of Suzanne and William at this very difficult time.
"The family members are being supported by specially-trained officers and I would ask that their privacy is respected.
"David Wyn Jones will be remanded in custody to appear before Caernarfon Crown Court on Monday. North Wales Police is not seeking anyone else in relation to this inquiry."
Friends and neighbours spoke of their shock at the death of Mrs Jones and her son.
David Thomas, 66, from the nearby village of Penmorfa, said he had known Mrs Jones since she was born.
He said: "Susi was born in this house here and she was a lovely girl who fitted into the community. You could not wish for a better full-time mother."
Asked about her husband, Mr Thomas said he had met David Jones for the first time when he visited the family's house last Tuesday.
"He was giving me advice on how to lose weight," he added.
Arthur Edwards, a 76-year-old retired factory worker who lives two doors from the terraced house outside Porthmadog where the incident happened, said: "They kept themselves to themselves, as people do nowadays.
"The boy William was such a happy little thing."
Mr Edwards told how he had seen police take Mrs Jones's husband away on Friday night. He said: "I saw him handcuffed, it was dark but he was wearing a white shirt and I could see it was him."
Another neighbour, who declined to be named, described Mrs Jones as an "absolutely dedicated mother".
Outside the house, which is set between mountains known as the Tremadog Slabs and fields with sheep grazing, friends and neighbours laid flowers.
One bouquet carried a handwritten tribute which read: "You were just young your baby to (sic).
"It saddens us your family to (sic). For you both it's been so short, so lives must go on regardlessly (sic)."
The note was signed: "Christina, Tomos, Anwen, Albert (Blue)."
Another tribute, signed Erin, said: "You were such a loving mother. Miss you both very much."
