Stranger in the Garden!

14°C  -  9 mph SSE Wind Speed  -  15 mph Gusts  -  Heavy Rain.  Took a shot of this stranger in between rain showers. It self-seeded in between my Mullien bed and the Feverfews, and came into bloom yesterday.  I’ve no idea what it is and it isn’t in either of the empty gardens beside me.  I’ve inserted a close-up to get a better view of the bloom. I like the soft colours of it and would really appreciate an opinion as to its name  -  please☺  I've since googled it and I think it is Angels Blush (Lychnis occulata) a type of Campion  -  can anyone verify?
