Does anyone know the record for the number of foals a mare throws and number of foals who win ?

In Gulfstreams 3rd race saturday, the dam of the #1 Historyofasaint, is Historic Mission. While she was unplaced as a runner, she has produced 14 starters and 12 winners. I don't recall ever seeing a higher number before. Is there such a record for such things at the Jockey Club ?
