Some researchers believe that Euphemia was the daughter of Bela's older brother Andrew I of Hungary and his wife Anastasia of Kiev, with the alternative name Adelhaid been proposed, due to minimal sources on her birth. Though the theory supported by most scholars and historians is that Euphemia was born as a result of a marriage between King Bela I and an unknown Piast Princess.
Together they have four children:
- Svatopluk, Duke of Bohemia (21 September 1109)
- Otto II the Black (18 February 1126)
- Bretislav
- Boleslava
Their youngest two children disappeared from written records and thus, are assumed to have died at a young age.
