Do not be so hastey to disconnect. Here is something to peruse.

Cousin Canute Valdmarsson, Duke of Estland Blekinge and Lolland 1205 - my 6th Cousin 20x removed

Svantepolk Knutsson Viby, Skarsholmsatten is my 7th cousin, 19x removed

CURATOR NOTE (Lasse Soderstrom) "There are no real sources for who Knut's wife is. The only indication is that his son's name SVANTEPOLK refers to Pomerelia.

So I matched my DNA to Euphemia Świętopełkówna von Rügen, Princess of Eastern Pomerania --- a Pomerelian close relative.

My 2nd cousin, 23x removed. Perhaps there is a path in my DNA to help determine the wife of Canutsen
