I haven't seen anything validating that Allen had a first name or that it was Edward. He is always seen as Allen McDonald, as far as I've seen.
Additionally, the connections here on Geni have errors. The family info on Find-a-Grave and Wiki have different info for the parents connected to Allen.
His father Alexander's details from those sites:

His mother Hannah's details from those sites:

My interest in these folks is that my son is a McDonald decendant on his dad's side, from the line of Alice (McDonald) Ingram. He and some cousins of his on Ancestry have at least a dozen DNA matches to folks whose trees seem to have copied from each other that they're descended on this line as connected here on Geni, which doesn't add up. The father connected here on Geni to Alexander Sells McDonald doesn't have a son named Alexander listed from any of his three marriages, all noted in his profile notes.
Just as I don't believe Allen was named Edward Allen, I don't think his father was named Alexander Sells McDonald. The Sells surname came into the line, as far as I've seen so far, from Allen's wife Susannah Sells and only then began to be used in the names of descendants.
There is nothing in the About section of the profile of Alexander Sells McDonald to validate the parental connections he has on Geni.
and his Find-a-Grave and Wiki pages have him born in 1768 in Virginia, not 1730 Scotland. In fact, these other sites show that Alexander and Hannah married 11 Oct 1798 in Jefferson County, Tennessee, which means if Allen's date of birth is correct here on Geni, he can't be their son.
This site doesn't go back father than listing Alexander's parents as Alexander I and wife Margaret Harrison, which concurs with Find-a-Grave and Wiki on that:

Desc. of Alexander McDONALD, II by Alan Vance McDONALD
1. Alexander McDonald II b. 25 Jul 1768, Beverly Manor, Orange County, Va, (son of Alexander McDonald I and Margaret Randolf/Harrison) m. 11 Oct 1798, in Jefferson Cnty, Tenn, Hannah Kirkpatrick, b. 6 Mar 1779, Watauga Cnty, N.C., d. JUN 1857, Green County, TN. Alexander died 5 Sep 1834, Whitesburg, Jefferson Cnty, TN.
My guess is that due to lack of documentation to help sort things out, some same-named guys have gotten confused and misconnected.
I haven't figured out how the folks claiming Allen and Susannah as their ancestors connect to my son since their trees have the same errors I feel are connected here on Geni. I don't know who copied who, but things don't add up.
If anyone has better documentation or any other additional info to share, that would be great.
Thanks in advance for any assitance in sorting these connections so they don't give incorrect or speculative connections here on Geni.
I fixed part of the problem. Allen was connected as a son of Hannah Kirkpatrick and Alexander McDonald. However, Hannah was connected to two different husbands both named Alexander McDonald. One is the correct one as determined by the info in my previous post. The confusion was coming from her also being connected to the one from Scotland, probably from one of the Gedcom uploads to the profiles.
I've disconnected the incorrect Alexander McDonald from Scotland as Hannah's husband. In the process, that detached her as the mother of this Allen McDonald, which makes sense given that she didn't marry her husband Alexander from Virginia until 1798 and they couldn't have been Allen's parents.
I don't know if Alexander McDonald b. 1730 Stranraer, Dumfries and Galloway, Scotland is truly Allen's father or if that Alexander's wife is Allen's mother. I could only determine that 'parents' married in 1798 couldn't have had Allen who is listed as born in 1776.
So I'll leave any further corrections to Allen's profile and lineage to his profile managers and descendants.
Allen's FInd-a-Grave page has his mother as Hannah Bell and his father as Alexander Sells McDonald:
https://www.findagrave.com/memorial/81692698/allen-mcdonald
I've seen Hannah listed as Hannah Bell (Kirkland) McDonald, but that's the Hannah who wasn't married to her Alexander until 1798. So it's possible that Hannah (Bell) McDonald and Hannah (Kirkland) McDonald have been mixed up just like the various Alexander McDonalds have been.
Hannah (Kirkland) McDonald was born 6 May1779 in Watauga, North Carolina, Hannah (Bell) McDonald was born 1736 Virginia, so definitely not the same woman.
I found Allen's Wiki page, which has his mother as Hannah (Bell) McDonald:

Now that I made those changes in my Ancestry tree, I got this Hint for the parents of his father Alexander:
