I love
Gillian and greatly prefer the G spelling; however, I also prefer
Jill with a J. Which can be very slightly confusing sometimes!
I've always fancied
Laura Gillian as a combo. And I've always thought that if one were fortunate enough to have twins, a good way to link them names-wise would be to use
Gillian for one and
Juliet for the other. It wouldn't much matter if they were fns or mns; I think of
Laura Gillian and
Tessa Juliet, but other possibilities exist -
Gillian Clare and
Juliet Anne, or
Gillian Ruth and
Juliet Rose. Or, of course,
Juliet Laura and
Gillian Tessa - they sound better in that order somehow.
