But kinglet Styr-Björn is estimated to Jomsborg and to his marriage with
Thyra Haralsdatter only about 985.
Probably Styr-Björn was all too young to have had a son who was adult
already in the 990s.>>
I don't think that marriage year is a well-founded estimate. I haven't
found anything that allows us to pinpoint it even within a decade. He was
her first husband, and she was married by 992 to Mieszko because he died that
year. Her parents dates are vague enough that her birthyear is also
vague, possibly as early as 935, or as late as 949 maybe even later as you say.
I just don't think we can pin it down.
Will
it is not too likely that her second and thir marriages would have taken
place she being already in forties or so.
And this (the year 992 and the earliest possible date -such as in mid-990s-
when she could have married Olav) actually pinpoints her to be in her
thirties or no more than thirty....
Which would favor her being born in about 965 and gettng given to marriage
wiuth her first husband in about 985
Moreover, sweden's Eric the Victorious cannot have lived to too an old age,
there is no indication that he were a geezer. But since he was co-king with
his bro, then saw his nephew Styr-Bjorn to grow up, then remained alive
after Styr-Bjorn.... and threw Svend forkbearded out of his kingdom, after
Styr-Bjorn's demise I think, this all means (as put into a reasonable reign
of perhaps thirty years) that styr-Bjorn must be rather in 980s than much
earlier.
I am of the opinion that these two personages: Thyra the thrice-married and
king Eric the survived-his-nephew, cannot be stretched to too long a life,
which pinpoints Styr-Bjorn and Thyra's first marriage to late dates.
