Pronounced eye-lo. What do you think of the name and which spelling do you think is the nicest?
And do you prefer it to [name_u]Arlo[/name_u]?
With the names ending in “O”, they read masculine to me and I would definitely assume [name_u]Arlo[/name_u] to be male. I think the spelling Islo would work best because it is so close to [name_f]Isla[/name_f] which everyone recognizes.
