Personally, no, I wouldn't use either name for a child which is a great shame. It does make me sad as I'd love to honour my mum, I just can't really get excited about the name Sarah
(and trust me I've tried hard) and I don't like that Jayne
has a 'Y' in it, it just seems unnecessary.
If I could rename my mum I'd probably keep her initials S.J. and name her something like Seren
. It has that first initial, it sounds similar to Sarah
and it reflects her Welsh nationality. I'd keep Jayne
but drop the 'Y' to Jane...or perhaps swap it for June
. Seren June
