Ed Joyce will hope to give England a flying start in the World Cup
It may come as a surprise to many cricket fans to find out Ed Joyce is not the first member of his family to play in a Cricket World Cup.
He is in fact the third - after his twin sisters Isobel and Cecelia represented Ireland Women.
And they will be offering advice to their 28-year-old older brother as he prepares to head off to the Caribbean with the rest of the England squad on 2 March.
"Isobel and I will be travelling in Australia but we'll be following the Ireland boys and Ed from Oz," Cecelia told BBC Sport.
"We both love Australia and were out there for the Melbourne Test although we missed Ed's maiden one day century against Australia in Sydney. It was our first ever holiday abroad because cricket has always come first."
Ed initially helped Ireland qualify for the World Cup, averaging nearly 100 in the ICC Trophy and scoring 60 against Denmark to seal Ireland's passage to the West Indies.
The Middlesex star was subsequently feted in Ireland, but then switched to England colours - as he qualifies by residence - and it hasn't engendered any bad feeling in his home country.
"Ed's still a big hero here" says Cecelia.
"Most people in Ireland hope Ed does well, and they want England to win the World Cup because realistically Ireland can't expect to get beyond the group stages.
"There's a sense of 'the boy done good' and lots of Irish cricket fans are proud that Ed has the ability to mix it with the best in the world."
"Ireland face Pakistan, West Indies and Zimbabwe, and I think the goal will be to claim one scalp, and that could well be Zimbabwe."
Cecelia hopes Ireland's men's team will find the going easier in the Caribbean than the women did in South Africa two years ago.
Ireland's women finished bottom of the table against tough opposition. Cecelia spent 80 balls making just eight runs against eventual winners Australia.
"It was a complete step up. Fast bowlers like Catherine Fitzpatrick bowled at twice as fast as anything I'd seen before.
"Just as in the men's game Australia have been so dominant. You can't help but admire them.
"But their men's one day form has slumped for some reason and I think the World Cup is set up to be really open and exciting."
