No. The "Limbo of the Fathers" is different from the Limbo of infants who die without baptism.
The "Limbo of the Fathers" was the temporary place or state of those people who were bound for heaven yet died before Christ opened the gates of heaven.
I just go with what Yeshua (Jesus) called it: She'ol (or Hades, which is not the same as what we think of as Hell), on the Abraham's Bosom side (Lk. 16:22, where He confirmed an old rabbinical tradition about the division of She'ol).
