BoothieBarn Retweet of Donation to ALPLM
"Dave Taylor has posted this retweet regarding the donation of a cane to the collection at the ALPLM. Hopefully, this will allow you to see the cane as well as read the provenance:

Thanks to Robert and Sherry Holt of Jefferson City, MO, for donating this cane! It belonged to Horatio Nelson Taft, whose young children often played with Willie and Tad Lincoln. An older Taft son, a doctor, helped treat #AbrahamLincoln after he was shot."


What were the names of those young children (there were three) who often played with Willie and Tad ?
Bonus points for the name of the older Taft son who was a doctor.
