Share 'Rescue English Setters'

My daughter has reserved two English Setters a dog 2 years old who has previously been rescued and a bitch 4 years (not previously a rescue). She has asked me for advice but only ever had Irish Setters I do not know about any differences. They are quite a bit smaller than my boy and they look as if a but of grooming is required. (Are they groomed the same as Irish)? Any advice would be helpful.
