Jane Houston Alexander (Hunter) - Who is she?

I am trying to determine whether "husband" John Alexander is the same as John Alexander

John Alexander is DAR patriot David Alexander David Alexander's son and married (per DAR) Mary Galloway Mary Alexander

John Alexander is attached to David Alexander, Sr as son and shows married to three profiles/women:
Jane Alexander Jane
Mary G ALexander Mary Galloway
Mary G. Alexander Mary Galloway

David Alexander, Sr http://services.dar.org/Public/DAR_Research/search_adb/?action=full... has TWO confirmed children with Margaret X:

1 RUTH [1] JOSEPH ACKER

2 ELEANOR [1] ARCHIBALD REED

David Alexander
http://services.dar.org/Public/DAR_Research/search_adb/?action=full... is husband of Martha X seen here as Martha Alexander maiden name Galloway
with ONE DAR proved child
John Alexander
JOHN [1] MARY GALLOWAY
whose profile I added today and checked the line of descent per DAR

David Alexander is seen as brother of John W. Alexander here and HE shows as http://services.dar.org/Public/DAR_Research/search_adb/?action=full... with one wife SUSANNA ALEXANDER
and ONE DAR proven child: SUSANNA [1] JAMES WASHINGTON PLUMMER

I asked a few days ago about Moses Alexander Colonel Moses James Alexander, I 's birthplace

I’m unable to merge the parents from my iPhone— a glitch?
I don’t typically even try but was doing what I was thinking to be quick clean up
Please see Colonel Moses James Alexander, I
Also, WAS he born in Maryland? Son attached shows son born in Ireland
-------------------------------------------------------------------------------------------------

I have completed the merge since that time but still am questioning Moses's info.
He is presently showing as my 7th great grandfather.
His attached parents profiles are curated.
Thank you.

Correction--- only Moses's attached father's profile is MP'd. Mother's profile is not.
