Can tu tell me about queen Elsie, short-term wife of King Olaf |||? Her maiden name was Bergen, and that's how the town of Bergen was named. But I want to know...

Why is her marriage to Olaf ||| so unknown, unlike Ingerid?
Did she have kids with o without Olaf |||?
If she had kids with Olaf |||, who? Where they heirs?
If she had kids without Olaf |||, with who? Who were they?
Was she a kind o cruel queen?
Who were her siblings?
Was she only a mistress, never queen? Hope not!
How old was she at her coronation?
How old was she at the end of her rein?
What's her early life like?

If tu can answer any one of these questions, please tell me. Thanks!
