Hannah Cathall, we feel certain, must have been a teacher of considerable merit. She began her service at least as early as 1765[1029] and in 1779 was still in that employment, being at that date engaged in a school with Rebecca Jones, for instructing girls in reading, writing, “and other branches suitable to them.”[1030] They also received poor girls sent by the overseers. Other mistresses employed by the board in 1779 were Sarah Lancaster, teaching the rudiments to young children of both sexes (sewing especially for girls), Essex Flower in a school similar to Lancaster’s, and Ann Rakestraw who had charge of a reading and spelling school.[1031] Sarah Lancaster still continued in the schools’ service in 1784, having in attendance sixty-four scholars, part of whom attended only half days. The other mistresses mentioned at that time were Mary Harry, teaching a school for children, Mrs. Clarke, teaching boys and girls, reading and sewing for the girls; Ann Marsh in a school similar to that of Mrs. Clarke’s, and Mary McDonnell, who taught fifteen young children, what studies we do not know.[1032] The committee’s report for that date shows that nearly one-half or perhaps more of the children attending the schools of the Friends’ masters and mistresses were children of the members of other denominations. In almost every case the teachers were Friends, or, as they termed it, “people of friendly persuasions.” [Sidenote: Mistresses in the Negro School] Mistresses devoted their abilities also to the instruction of the Negro children. Sarah Dougherty was for a time (about 1790) employed in the Negro School, but for some reason, unexplained, Elizabeth Meccum was employed in her stead.[1033] Elizabeth Meccum remained in that capacity till the time of her death, which occurred between 1795 and 1798.[1034] Joseph Foulke, in a letter concerning his schooling at Gwynedd Meeting, mentions Hannah Lukens who kept a “family school” and also Hannah Foulke,[1035] both of whom were members of Gwynedd, but further information of them the writer does not have.
