They do look alike. They are quite closely related.
Albert Victor, Duke of Clarence is the son of Britain's Queen Alexandra from Denmark.
Alexandra is the first cousin of Prince Frederick Charles of Hesse-Kassel.
I always think that Lord Frederick and his father, Prince Michael of Kent, look like Albert Victor too.
They both have a connection to the Hesse-Kassel line and Christian IX of Denmark.
Nicholas II of Russia looks similar with shared bloodlines as well.
Thanks Cloaked and Pede for the info and pictures. I knew there was a Hesse connection through Princess Louise of Hesse-Kasse. The resemblance between the two is remarkable. I had just been reading about Prince Albert Victor being one of the potential suspects in the Jack the Ripper murders, so when I saw the picture of Prince Frederick Charles of Hesse Pede posted, I was quite surprised.

Miss Waynfleet, I just read through the thread again and realized that's it's you who provides the pics of the Wales & Hesse cousins.
Sorry for overlooking you and thanks. Can't give you a star until after 24 hrs but still
