Myre or Myra Ackerman of Michigan or Pittsburgh Pa

Hello
I'm looking for info on Myra (Myre) not sure of the spelling Ackerman. Just received info that she is my hubby's grandmother. She married Joseph Cooper of either Mi or Pa. We are looking for their children (who would be our Aunts and Uncles)
Her son MelvinG Cooper is my hubby father.We were able to find out about one of the Uncle Winfield Cooper but not any of the others.
There names are
LorettaZella (Zelda not sure of the spellin) Clinton, Hugh
Dolores (aka Pat) Melvin (as above)
But there are others any and all info would be appreciated
Thanks in advance
Jan
