Kenny had a couple of bogeys and a double at the 11th, but made amends with a handful of birdies, while Caithness, eighth in Slovakia last week, recovered from dropping shots at her first two holes to also finish in a tie for ninth place and just three shots behind the surprise leader, Ireland's Hazel Kavanagh.
But it was a disappointing opening day for Vikki Laing. The Musselburgh golfer had three bogeys and a double-bogey and managed only one birdie – at the 18th – in a 77 that left her with a tough task to make the cut.
Carly Booth, the Comrie 17-year-old, who has made the cut in her first three appearances as a professional, produced another solid effort with a 74, while fellow Scottish rookie, Kylie Walker had a 76.
Laura Davies, who has already won in Germany and New Zealand this season, was in a three-way tie for second on 69 after a five birdie round and Trish Johnson, was in the next group on 70.
