Looking for a lost friend

Hello everybody this is a great site. 

My name is Sonya.

I am looking for a very good friend.

She is Bosnian / Serbian.

We used to work together in Werilla.

We used to travel to work in my car.

This was in 1970.

Her name is Ljubinka. She was married. No children.

At that time she wore black clothes and a black scarf.

She has two brothers. I met her younger brother Mirka.

The older brother is Budimir.

At that time they all lived in the same house in Warrawong near the plaza.

I know her brother Mirka would be 72 years of age now.

I used to live there but in 1972 I moved to Sydney.

Then I moved to Melbourne and we lost touch.

I would love to see them a lot to see how they are now.

Anybody with any information please private message myself.

Thank you everyone.
