10th: What do you make of this?

What would you interpret the forenames of the above squiggle as?

He is enumerated in the 1852 Hull, Quebec census, a few entries below Jane FAIRBURN (aka FAIRBAIRN) with her assumed sons James (later married Mary SMITH, Jane's niece via her sister Agnes SMITH nee WILLIAMSON) and John (married Sarah DAUGHTERTY and moved to Stillwater, Washington).

We'd like to prove that he is Jane's son, hopefully with an extant death cert or obit. that conclusively states whether Jane was married to John or David FAIRBAIRN.

New information found (see re John's son John) has led to a re-evaluation of supposedly known information for this family.

With records indicating that there was both a John and a David in the area, and assorted records assigning their assumed families indiscriminately between the two, and often with the wife for both being Jane WILLIAMSON, it's been an interesting exercise.

The jury is most definitely still out, but tending to Jane being married to a John, who seems to have died in 1847, from a fall from a horse if newly received information is accurate.

Children Agnes, James and John rather look like they belong to John and Jane, with possibly Archibald (marr. Margaret GRAHAM) and William George (marr. Sarah FARRELL) belonging to David and wife unknown..

David marr. to Charity WALKER could belong to either, but I'm currently leaning towards him being John and Jane's!

Anyone with hard facts about these families? The family information is rather contradictory, one even throwing an Archie in as married to Jane WILLIAMSON.
