know about something ***

I am what others have known and felt about me.

Very little is known about the period between 700 and 1000.

But they have not known much about her early life.

By the end of the 6th century nothing more was known about them.

Another thing she hadn't known about her father, his state of mind.

Not much is known about the history of the town before the 18th century.

Not much is known about the history until the 18th century.

Not much is known about these last years of her life.

I think deep down my mother must have always known about me, but on another level she never knew at all.

Lives had been lost during the war because they hadn't known enough about such things.
