[name_u]Love[/name_u] the nickname [name_m]Harry[/name_m]. But not as a standalone. Any ideas for full names? We like [name_m]Harrison[/name_m] and [name_m]Hawthorn[/name_m], but they still don’t feel “right”.
[name_m]Harold[/name_m], [name_m]Harris[/name_m] or [name_m]Henry[/name_m] maybe?
I really like [name_m]Harrison[/name_m]. Other ideas:
[name_m]Hardy[/name_m]
[name_m]Harlan[/name_m]
[name_u]Harley[/name_u]
[name_u]Harper[/name_u]
[name_m]Hart[/name_m]
[name_m]Harvey[/name_m]
[name_m]Harris[/name_m] sounds awesome! 
I would go with [name_m]Henry[/name_m] or [name_m]Harold[/name_m]. [name_m]Henry[/name_m] is the main name I associate with the nn [name_m]Harry[/name_m].
[name_m]Harrington[/name_m] is the only one I can think of
