They seem to have been cousins of the more famous Lucretia, but their importance for Albany is greater as far as local efforts are concerned. What they did in western Albany County with the underground railroad we do not know specifically, but Phillips identifies that fugitives did find refuge in that area. The work of the sisters in connection with temperance meetings is also noted in Howell and Tunney's history of Albany. Lydia and Abigale are in Siebert's list of underground railroad operators as active in the Albany area. Unfortunately there is no other reference in Siebert regarding the Motts.
Information has to be gathered from other sources.
This book, published in 1987, collects short writings from primary sources which tell stories about fugitive escapes from slavery. One account is that of Austin Bearse. Mr. Bearse was a native of Massachusetts and a commercial sailor. Sometimes the boats he worked on were involved in shipping in the south and sometimes slaves. The treatment of slaves was revolting to him but he said little of it until after 1834 when he began reading the Liberator.
