Quoting my email from earlier:
'Yesterday somebody tried to attach a second William Armstrong to the family of DAR patriot Pvt. Daniel Armstrong. After I disconnected him I went looking for where he probably really came from, and wasn't surprised to find an immigration record from 1808 (he married in 1809).
One thing led to another and now there's a whole family of Armstrongs that arrived in 1808, most of whom settled in Ohio. And this is where it gets sticky, because three of them married in Ross County, Ohio - the same county Daniel died in. Two children previously attributed to Daniel seemed to really belong to James, according to the immigration record.
I checked DAR and absolutely NO children are listed for Daniel, which is also probably wrong. I checked FamilySearch and the evidence for Daniel being the father of the children I think really belong to James is almost zero.
Daniel and James were cousins anyway so it doesn't matter too much but I think it's worth having another pair of eyes review this. Martin's profile has the full discussion, and there's a link to Daniel in James's profile.'
