John Johnson - Parentage

It appears that there were two men in Andover named John Johnson around 1786 - John, 3rd Johnson, Jr. who was born in 1748 and a widower, and John Johnson

https://mhl.org/sites/default/files/files/Abbott/Johnson%20Family.pdf (page 13) has John 1748 with only one wife, Hannah Abbott the daughter of John Abbott, Jr

https://services.dar.org/Public/DAR_Research/search_adb/default.cfm... has the John Johnson who married Abigail Johnson as being born in Boston in 1758 and marrying in 1786.

http://sites.rootsmagic.com/colonialgenealogy/individual.php?p=17534 appears to have conflated the two men named John Johnson.

Any further help to determine which one is the husband of Abigail (Abbott) Johnson would be greatly appreciated.
