I seem to have come across a million Lachie's in the last couple months (one spelled Lachy but mostly Lachie), its a quite common name here in Australia and I've always had at least one in every grade all through school (2000s and 2010s) but I swear recently its been everywhere.
I'd never use it but I think its a good name.
Thoughts?
