My gr. gr. gr.gr grandmother has always remained unknown to me, because the information I have been given about her refers to her as "Marcy Unknown" with Marcy as a diminuitive of Marcia.It has begun to dawn on me that referring to her as "Unknown Marcy" is much more plausible, one reason being that Marcia was not a commonly used first name at that time. The Marcy I am talking about was born about 1760 and married about 1777 Abraham Jones.Abraham Jones, b. 17 Sep 1758, was the son of Josiah Jones and Hannah Richardson Jones.Josiah was the son of Robert Jones, b. Denbighshire, Wales 1695, who married Gwynedd Friends Meeting, Philadelphia, now Montgomery, County PA 22 Aug 1717 Anne Coulston, b. Yorkshire England, 1695, daughter of William Coulston. Abraham and Marcy Jones had 7 children: Josiah b. 01 May 1779, Hannah b. 05 Jul 1781, Ann b. 13 May 1784, Isreal b. 09 Jan 1787, John b. 20 Nov 1787, Rosannah b. 04 Jun 1789, and Margret b. 24 Jan 1794.In the First U. S. Federal Census in 1790. Abraham was listed as a Head of Family in Montgomery County PA.Marcy died in 1794. Can you provide any information that would prove or disprove that my gr. gr. gr. gr.grandmother Mardy was of the Marcy family? Iwould appreciate your help very much.
