Pedigree Query

Am I right that she was the last or about the last important horse from the Hanover sire line? And that Wise Counsellor, her grandsire, was the last major sire from that line?

Stepwisely may be the most recent MSW-producing Thoroughbred mare whose sire traces in tail male to Hanover. HoF QH Go Man Go's unregistered dam was by Wise Counsellor's son Very Wise. GMG and Bolero are the most frequent sources of Wise Counsellor in their breeds and WC could quite reasonably be considered the last major sire from Hanover's line.
