Twin sisters died within days of each other after both falling ill with coronavirus.
Eleanor Andrews and Eileen, 66, 'did everything together' and are believed to have contracted the virus at the home they shared together.
Eleanor's son Stuart said his mother was the first to show symptoms and died on March 29. Four days later Eileen passed away after being admitted to hospital.
Both sisters had underlying health conditions linked to their age.
Stuart, of Abercynon, near Pontypridd, said: 'It doesn't feel real. It's beginning to take its toll on us and it's getting harder every day.'
Eileen's brother Phillip, 68, is now in hospital after also testing positive.

Another 938 people who tested positive with Covid-19 have died, taking the total to 7,097
Stuart said: 'It's terrible, he was still up and about, he was active and to see him go like this you'd think he was a totally different person.
'You think "it's not going to happen to me - it's not going to happen to me" because things like this don't happen to us but it does, it does happen.
'Just stay in, because this is the effect of people not staying in, and not listening to the Government. We don't want to put people through what we are going through.'
Stuart's wife Janice compared the experience to a 'horror film or a nightmare'. She described how Eileen deteriorated rapidly while she was being treated in hospital.
'We spoke to her on the telephone at about 8.15pm. She was on oxygen and we couldn't make much out,' Janice said.
Both sisters had underlying health conditions linked to their age, close family have said
'They rang us at 9.15pm and said she was sat up asking for tea and jelly. Twenty five minutes later she had passed away.
Stuart said how both women will not enjoy the funeral that they deserve.
'It has to be a closed funeral and there is only six allowed with the vicar or reverend. There will obviously no wake, no cars, that's all you can do,' she said.
It comes amid news today that 938 more people who tested positive with Covid-19 have died, taking the total number of fatalities to 7,097.
NHS England confirmed 828 more people have died in its hospitals, with patients aged between 22 and 103 years old and of whom 42 had been otherwise healthy.
Scotland, where 77 more deaths have been confirmed, also diagnosed a further 336 infections in the past 24 hours, Public Health Wales announced 284 more positive tests and 33 deaths, while five more fatalities were recorded in Northern Ireland.
Today's surge in deaths brings Britain within distance of the worst days experienced in Europe, which saw 969 deaths in Italy on March 28 and 950 in Spain on April 2.
China never recorded more than 254 in a day. But the numbers are dwarfed by the US, which is being hammered by the virus and recorded 1,799 deaths yesterday.

Despite another dark day in terms of new diagnoses and deaths, deputy chief scientific adviser, Prof Angela McLean, said that the numbers of people being admitted to hospital are steady and the spread of the virus 'is not accelerating'.
The PM remains on an intensive care unit in a central London hospital, where his spokesman says he is in a stable condition and 'responding to treatment'. He was admitted on Monday night after suffering a fever for 10 days.
Attention has now turned to Mr Johnson's vow to evaluate the progress of the UK's lockdown next week, which it looks like he will be unable to do.
Downing Street says it will delay the evaluation, while London Mayor Sadiq Khan has claimed that the UK is 'nowhere near' the end.
The Government's instructions to stay at home during the coronavirus pandemic are among the most drastic ever imposed in UK history.
