In public, I say them all like mad uh lin unless I’m in a [name_m]French[/name_m] speaking area… in which I would say [name_f]Madeleine[/name_f] more like mad-len. In my head I will always use the line ending for [name_f]Madeline[/name_f] though 
[name_f]Lynn[/name_f] for it makes no sense in my head!
[name_f]Madeleine[/name_f] is by far my favorite spelling, though I also love other similar names like [name_f]Madelaine[/name_f], [name_f]Maddalena[/name_f], [name_f]Magdalen[/name_f], and [name_f]Madelief[/name_f] too. I’m a big fan of [name_f]Madeleine[/name_f] [name_f]Alba[/name_f] nn [name_f]Della[/name_f]
