Margaret, widow of the late Robert Griffith of Sygyn, was granted Administration of his personal estate in Dec 1670.
Named as a beneficiary in her father's Will (written 1686), receiving from him all right, title, claim and interest in a parcel of land with the appurtenances called Cae dû situated in the parish of Beddgelert in county Merioneth and adjoining a messuage or tenement called Sygyn.
A number of sources, primarily J. E. Griffith, indicate Robert Griffith having married Catherine daughter of Evan Lloyd of Rhiwgoch, and that Robert and Catherine were parents of Griffith Roberts who married Jane Glynne. However, the extant wills indicate otherwise. Furthermore, some secondary sources show Catherine Lloyd's mother as Ellin Salisbury (wife of Evan Lloyd of Rhiwgoch), making Catherine a sister of Robert Lloyd of Rhiwgoch who was already an adult in 1586. This is chronologically impossibe.
Catherine Lloyd wrote her Will in 1700 and in it she refers to her nephew Griffith Roberts to whom Administration of her personal estate was granted as guardian of the executor, Robert Roberts, who was Catherine's youngest son and at the time still a minor. Catherine also names her niece Jane Roberts als. Glynne of Rhiwgôch (i.e. wife of her said nephew Griffith Roberts).
Catherine Lloyd was the wife of Robert Thomas of Trawsfynydd, gent., and sole Executrix of his Will in 1692. Robert Thomas refers to their daughter Margaret Roberts as granddaughter of Evan Lloyd lately deceased, such that Margaret Roberts's mother was evidently a daughter of Evan Lloyd of Rhiwgoch who died in 1690 and therefore could not have have been the Evan Lloyd of Rhiwgoch who fathered Robert Lloyd of Rhiwgoch abovementioned, but was Robert's grandson who was also known as Evan Lloyd of Rhiwgoch. Catherine Lloyd is not named in her father's Will; Evan Lloyd does however refer to his son-in-law Robert Thomas.
It would appear that Griffith Roberts was not the son of Catherine but rather of her sister Margaret Lloyd (who names Catherine in her own Will as well as Catherine's daughter Margaret Roberts). It has already been noted above that Margaret was the widow of Robert Griffith of Sygyn when Administration of his personal estate was granted to her. In her own Will (below), Margaret identifies Griffith Roberts as her son.
