THIS INFORMATION HAS COME UP TO DISPUTE THE ABOVE: Ignatius, son of Samuel and Elizabeth Luckett was born 30 Jan 1689; brother Samuel was born 10 Oct 1685; and brother Thoams was born 12 Aug 1688. This from ook Q #1, containing Birth Records of Charles County, MD.
If Sarah was a Luckett, and since she was born cir 1668, this might make her a sister of the Samuel who was the father of the above named sons, but in any event, it looks as if she might have come from an earlier generation than those supposed to have been her brothers. Although she might have been a daughter from a previous marriage of Samuel. NONE OF THIS IS PROVEN, and included here as information only.
