Christian Susanna - Though has a historical use as a girls' name (particularly in Scotland, a bit of useless and irrelevent information here but according to the Edinburgh Uni witch survey there were 69 female witches called
Christian between 1563-1736), I still prefer it as a boys' name (though the more I think about it, it does sound nice, in a Early Modern sort of way). It sounds nicel with
Susanna. But as others have pointed out it doesn't sound good with
Bishop,
Christian Bishop sounds more like a label.
Sarah-Rose
Magdalena - this is nice
Kate Jeanne - too choppy,
Katherine Jeanne nn
Kate would be better, or
Catriona Jeanne, or even
Kathleen Jeanne.
