hmmm.
here are my thoughts:
Seamus - love the name, love Seamus Heaney - but it's the Irish form of James which means 'usurper' - not the nicest of meanings.
Magnus - love it, it sounds very mythical/ regal but does it sound a little ponderous? My other 2 dcs have quite mythical-sounding names but they both sound quite swift, quite fleet of foot if that makes at any sense at all??!! Worried that Magnus sounds a little heavy?
Atticus - not sure whether I love the name or whether it's my lifelong crush on Atticus Finch and Gregory Peck. I think it's the name too. And I like the meaning, too.
Anyone else?
