As a woman you have no ability in theology, and it is the teaching of the Church that women should not take part in theological debates.
Firstly, the Church has never defined where Limbo are located. Secondly, the council of Florence is often quoted by anticlerical men who try to convey the idea that according to the Church doctrine, all those who die in original sin are punished in hell, even if they have committed no actual sin during their lives; the problem is that this idea is wrong and since Saint Thomas the theologians do not claim anymore that children who die in original sin are punished in hell. This idea is blasphemous and disgusting, and yet it was prevailing before the time of St. Thomas.
Most traditionalists do not understand well the infallibility of the Church, especially laymen. The purpose of the Council of Florence was not to define any doctrine about Limbo, as this guy explains
here. The purpose of this sentence was only to define a particular point regarding the timing of the judgment; therefore it has a broad sense, and it is not meant to settle the issue of Limbo.
