Well, no. What Tubman did was un-matchable and deserves all the credit and attention, possible.
However, MEP -and both her spouses- spent many months and years working on the UGRR. They did transport many ex-slave fugitives to Canada and even bought property up there for immigrant purposes. They helped fugitives in California too. Mary Ellen and JJ Pleasant deserve recognition for this work- as I hope other stories of the UGRR are uncovered. I hope they can both be included in future stories of the UGRR along with others yet to surface.
