My mother has recently passed away and I am looking for her relatives.

She was born in a small village in Pusan? in/about 1947.

Her mother's name as I recall was Ki Boon Bek?

Her father was killed on a motorcycle (hit by either a bus, or a motor vehicle).

Her mother and sister came to the U.S. to visit us back in/about 1986.

That is the last time she saw any of her her family.
