What about LouisaMoira Plum? A bit "edgier" than Maureen, but still closely related.I actually love LouisaMaureen Plum best. I think the flow is great and it has a boatload of personality.
I had thought of Moira and I know it's the only one my mom would actually think is honouring her because she's spoken of how she loves the name before...think that's definitely an option. And glad to hear you like LouisaMaureen Plum....I'm actually really warming to it as well- thanks so much!!!
