The winger is also joined by Melrose fullback Chloe Rollie in the women's squad, which was named today (Wednesday).

Mhairi made her international debut in the away warm-up match against Italy in autumn 2014.

And Chloe has worked her way through the schools and age-group teams.

The more experienced Melrose duo of Lana Skeldon and Gillian Inglis, along with Lisa Robertson, from Galashiels, who plays for Murrayfield Wanderers, maintain their places in the squad. The Scotland Women squad for the 6 Nations includes a mix of experience and relatively newer faces.

Worcester prop Tracy Balmer captains the squad again, lining up in the front row alongside 71-times capped Heather Lockhart while back row Rachael Cook – who hails from Larbert Academy and was part of the Scotland Women under-20 side who defeated Finland two years ago – will be looking to add to her five caps won last season.

In the backs, stand-off Lisa Martin – who secured the first of her 19 caps as replacement for Scotland's most capped player, Donna Kennedy, during the latter's final match at the 2010 Women's Rugby World Cup – is joined by Mhairi and Chloe as well as outside centre Nuala Deans (Wasps).

Head coach Jules Maxton said: "We've named a squad that's an exciting mix of experience and youth.

"The first few months of our season have seen us play Italy away – a valuable experience – stage a number of camps and take part in a training game with the Nomads.

"All our preparations have gone well and the build-up to the 6 Nations concludes with a camp at the end of this month, before our opening game, away against France.” The 2014/15 Scotland Women international programme kicked off in early August with a four-day training camp, a two-day camp in September and a three-day camp in October which included a friendly at BT Murrayfield against an Irish Exiles side, won 49-0 by the home side.

A second Autumn friendly, away against Italy, took place in November, backed up with training camps at either end of January.

The sharp end of the senior Scotland Women's season begins on Saturday, February 7 in France with their opening match of the 2015 6 Nations, before returning to a new home base in central Scotland.

Following the away opener, the Scots then have two home fixtures, against Wales (Saturday, February 14, kick-off 5pm) and Italy (Sunday, March 1, kick-off 1pm) at the central location of Broadwood Stadium in Cumbernauld.

Scotland's remaining away match is against World Cup winners England, at the Northern Echo Arena in Darlington (Friday, March 13, kick-off 7.35pm) and is the second of a double-header at the stadium that evening, preceded by the under-20 international fixture between Scotland and England.

Finally Scotland return to Broadwood, where they're at home to Ireland on Sunday, March 22 (kick-off 1pm).
