Who are David GLASGOW and Janet HOOD's parents?

After 15 months there has been no additional information on this family supplied so I have detached them from their multiple parents and added 4 placeholders and relationship locked the profiles.

Here are links to the 4 placeholder profiles
* {unknown father of David Glasgow}
* {unknown mother of David Glasgow}
* {unknown father of Janet Hood}
* {unknown mother of Janet Hood}

If you have any evidence on who their parents are, please add it to this discussion so we can put the correct parents onto the profiles.

I could find no Abraham Glasgow on Family Search but here is David Glagow the spelling is just bad (Daved Glasgou)
