Greetings from Downunder, Anastasija.Wrenn looks lovely...I had one called the same, about 23 years ago.Her name was Amhurst Rendition, Wren for short.
I have a friend who owns one of my Irish, who comes from Croatia.She lives about twenty minutes from me here in Western Australia.
I was very happy to hear that someone has/had an Irish Setter called Wrenn. She doesn't have any other names. My Wrenn is very gentle, fine and friendly. She's a real girl. Your dogs are lovely and I see that you are a real Setter expert.
Best regards from Europe to you, your nice dogs and to your friend from Croatia
(p.s. that's my name for short)
