Esther is said to be the daughter of William Guthrie of Guthriesville in Chester County. She was born in 1802 in Penn's Valley and married Robert Wilson Moore in 1827. Many researchers show her mother as Esther McClelland but that could not be true as Esther McClelland died before 1800. Who is Esther Guthrie's mother and how does her father relate to the many other Guthries in the Chester County area?
