I adore the name [name_f]Marilyn[/name_f] (perhaps heavily influenced by [name_f]Marilyn[/name_f] [name_u]Monroe[/name_u]) but I love it still. However, I’m not overly keen on her nn’s ([name_f]Mary[/name_f], [name_u]Lyn[/name_u] etc.), so what nn’s could I use that arent too far a stretch. Thank you!

Please forgive repeats. My first thoughts were:
[name_f]Molly[/name_f]
[name_f]Mimi[/name_f]
[name_f]Mae[/name_f]
[name_f]Polly[/name_f]
[name_u]Marley[/name_u]
The only two I thought of that haven’t been mentioned yet are [name_f]Lindy[/name_f] and [name_f]Maya[/name_f].
I like [name_u]Marley[/name_u] the most for [name_f]Marilyn[/name_f]. 
What about [name_f]Mira[/name_f]?
I just have to butt in and say I have [name_u]Riley[/name_u] as a nickname for [name_f]Marilyn[/name_f]. It comes from the [name_m]RILY[/name_m] part (duh) but I read somewhere that someone had a child called [name_m]Rily[/name_m] in which each letter stands for [name_f]Remember[/name_f] I [name_u]Love[/name_u] You, so my [name_u]RILEY[/name_u] is [name_f]Remember[/name_f] I [name_u]Love[/name_u] Especially You.
[name_u]Marley[/name_u] is also an amazing nickname for [name_f]Marilyn[/name_f], can’t believe I missed that.
My first thought was [name_f]Minnie[/name_f]!
[name_u]Mars[/name_u] or [name_f]Mina[/name_f] (pronounced [name_u]Min[/name_u]-a, not meena)
[name_u]Arly[/name_u], maybe pronounced air-lee.
