b.1750 Augusta County, Virginia
Facts and Events
Andrew Edmiston was the son of John Edmiston and Margaret. He served as a Captain at King's Mountain under his brother then Major William Edmiston, in Campbell's regiment. There were apparently no issue from this marriage. His name does not appear among the signatories of the Ebbing Springs Call which probably indicates he was not an adult at that time. He was killed at King's Mountain....
Wife and Childen
Most lineages listed at Ancestry  give Andrews DOB as between 1740 and 1750. At a minimum, these DOB's would make him 30 years of age at the time of his death, and we would have expected him to have taken a wife at this time. Some lineages identify his wife as "Ann". This may be based on a deed record transcribed by at least one genealogist as:
p. 123 1784 Dower of Ann PATTERSON laid off in lands of late husband Andrew EDMISTON, dec. USGenWeb citing Washington Co. Va. Deed Bk. 1 part 1 1778-1797
This is consistent with Andrew (2), killed at King's Mountain, and suggests that his wife Ann had remarried following his death to a Patterson. However, the above transciption may be question, as it is in some disagreement with a transcription made by Summers, who gives it as:
Summers gives no date for this record, but all surrounding dates for other records are for 1789 and (less commonly) 1788, and not 1784, making the first transcription suspect. More critically, the wording in Summers transcription is considerably different from that cited above...and Summers does not identify Ann's late husband by name. That may be an error on Summers part, but it is also possible that the first transcription has become corrupted with "Andrew Edmiston" inserted as an inference. Transcriptions. Most likely, Ann is indeed Andrew's wife, but the original records need to be examined to verify the transcriptions.
Some genealogists identify children for Andrew, viz:
A will for Andrew has not been located as yet. However, there is a reference to his estate:
This indicates that a John Edmondson, Jr. is heir to Andrew Edmondson. This could be the John Edmiston b. 1774, identified by some as a son of Andrew, he would have been under age at the time the survey was finalized. That probably indicates that he's not the son of Andrew, but another kinsman. Additional work is needed to confirm the identity of Andrews wife and children. See Rambling Roots for one example where John is identified as Andrews son.
Hard data for Andrew is quite limited.
Summers 1903:327 lists him as an ensign among those killed that day.
