Of the suggestions thus far I love the following:
Henry, Sebastian, Edward.
Arthur is eldest's middle name. Also, do we think it matters to have two H's or two A's??
See, I just realised I am presuming another boy!
Girl's names I love Harriet, Beatrice, Violet, Maggie, Rose.
I have really exposed myself on this thread so if you know me, don't crack on I am pg to the world outside the web. Literally only found out yesterday and told no-one except you lot! Very early on but the names thing makes it feel real.
Thanks for all the lovely suggestions.
