Edinburgh judoka Kimberley Renicks won gold for Scotland in the women's under-48kgs Commonwealth Games final with victory over India's Sushila Likmabam.
Renicks, the younger of two sisters in the Scottish team, scored an ippon throw to the delight of the partisan crowd at the SECC venue, as the hosts landed their first gold at Glasgow 2014.
In the bronze medal contests, Amy Meyer of Australia defeated Barbados fighter Onoh-Obasi Okey on shido penalties, while compatriot Chloe Rayner beat Marcelle Monabang of Cameroon with a waza-ari hip throw score.
Ashley McKenzie won gold for England in the under-60kgs with a shido penalty victory over Navjot Chana after an edgy contest.
The Indian had gone ahead with a 10-point waza-ari score, only for McKenzie to quickly go on the offensive and the Londoner thought he had won the contest with a hip throw, given as ippon, but was then downgraded after a lengthy review.
Eventually the scoreboard was reset, and McKenzie kept his cool to close out victory as Chana racked up three penalty scores.
The Scotland fans were earlier on their feet again as veteran John Buchanan won bronze in the same class.
The 39-year-old Edinburgh Sportif Judo coach came out of a decade-long retirement to fight in Glasgow, and his endeavour was rewarded as he defeated beaten semi-finalist Daniel Le Grange of South Africa with an ippon score, given on video review - and promptly did a full back-flip on the tatami mat in celebration.
Razak Abugiri of Ghana took the other bronze as he beat Neuso Sigauque of Mozambique.
Renicks was watched on by father Thomas, founder and sensei at the Kanokwai Judo Club in Strathclyde, with elder daughter Louise also preparing for a gold-medal contest in the under-52kgs division.
"It is absolutely brilliant. It is what I had been hoping for and what I have wanted for the last two years," Kimberley Renicks told Press Association Sport.
"The crowd have been behind all of us and it has been a great start to the Commonwealth Games.
"I could not have done it without Team Scotland and Judo Scotland, all of the fans, the family who have supported me all the way.
"If they had not put the effort in to get me to all of these places, I would not have been here today."
She added: "It has been really tough, because I was against girls I had never fought before, so you don't know how they are going to be.
"In judo you can win in the first 10 seconds or last four minutes, and I happened to win my fights pretty fast, which was good."
Louise Renicks completed the family double with victory over Kelly Edwards in the under-52kgs final, with the English fighter disqualified after collecting four penalties.
Both women were cautioned by the referee for various infringements, which now include leaving the yellow combat zone.
There were just three seconds left of regulation time when Edwards picked up a fourth shido, for a false attack, handing gold to the Scot.
Northern Ireland secured a first bronze medal of the Games as Lisa Kearney, who fights out of Edinburgh, beat Canada's Audree Francis-Methot.
Kalpana Thoudam of India took the other bronze, defeating Mauritius judoka Christianne Blegentil.
Renicks said of her victory: "I have always believed I could get this medal, now I have got it, my job is done, and I am feeling brilliant, really proud of myself.
"I watched a bit of my sister's fight, where she won and then got her medal, but I had to keep myself focused.
"My mum and dad are here, and it is a really emotional moment, I was a bit upset when I came off the mat.
"I heard the Brownlee brothers won for England tonight, so now it is two families who can celebrate.
"I feel really proud with us getting the first gold medals for Scotland and there is much more to come."
Colin Oates won gold for England at under-66kgs when he defeated Andreas Krassas of Cyprus with a quick throw and armlock combination.
Oates, brought up in Norfolk, but now fighting out of the Edinburgh Ratho club, had reached the Olympic quarter-finals, since when he has steadily climbed the world rankings.
The 31-year-old produced some strong Ne Waza groundwork en route to the final, and followed that up with another impressive display to continue the home nation domination of the Judo competition.
Scotland collected another bronze medal when James Millar - a late call-up for Scotland as replacement for the injured 100kg judoka James Austin - defeated Mathews Bpunza of Zambia with a late ippon throw.
The other under-66kgs bronze went to Siyabulela Mabulu of South Africa, who defeated India's Manjeet Anandal.
Gold in the women's under-57kgs went to England's Nekoda Davis, who beat Scot Stephanie Inglis.
Davis, based at British Judo's Centre of Excellence in Walsall, scored a Waza-ari throw, which she followed up with a 25-seconds hold-down to clinch the title.
