Blessed Gebhard of Salzburg, also occasionally known as Gebhard of Helfenstein (estimated date of birth about 1010; died 15 June 1088) was Archbishop of Salzburg. Of Gebhard's origins, all that is known for certain is that he was born in the Duchy of Swabia. Although it is sometimes suggested that he was born the Count of Helfenstein, this is entirely speculative. Wikipedia
