It is recorded that when R’ Yackov Kamenetzky Z’l was ill, at the minyan of R’ Moshe z’l they were making a mi sheberach for him. They didnt know his mothers name. R’ moshe told them to make a mi sheberach for “R’ Yackov”, the ribbono shel olam knows who we mean. I assume the same is true for mack goldstien.
