Struggling with an abbreviation (two letters)

[Gateaux23]

The first image is from a 1749 marriage record in Glen Urquhart, Inverness-shire. Marriage between Andrew Urquhart and Margaret McDonald alias Dow. After each persons name there is something that looks like "Gn.". I can't quite make it out or have a clue what it means. No other persons on this page from the marriage registry have this after their names.

The second image dates from 1755 and is the baptism record of his son who had the cool name of Farquhar Urquhart. Something I can't read, and which seem to be related to the above abbreviation, is written after the father's name.

Any ideas?

The second image is, I am sure, the abbreviation for Junior.  Possibly also for the first, but not so sure of that.

I also thought junior for both before seeing BumbleB’s thoughts

jn for 1 and jun for 2

Added, or no 1 could be “yn” for younger?

Junior surely doesn't make much sense, in the second one at least, as he has a different name from his father.

Junior surely doesn't make much sense, in the second one at least, as he has a different name from his father.

But there could be other older relatives of the same name.

I initially thought "younger" but not sure what the dash and the two dots mean. Unless it's an abbreviation for 1st or 2nd born or something like that. Though if it were that it doesn't answer why it doesn't appear in the other marriage records.

Use of the word "junior" doesn't necessarily imply a blood connection?

My mother was known, by some, as "Mrs Garrad junior" to distinguish her from her mother-in-law. 

[Gateaux23]

I thought the first read "Junr." an abbreviation of Junior. However, I've looked at hundreds of marriages in this parish and have never seem someone referred to as junior. It really sticks out like the worst sore thumb ever. Things normally go "Joe Bloggs son of", "Joe Bloggs in someplace", or rarely "Joe Bloggs with occupation". Junior and Younger just don't seem to fit the usual pattern.

My attempts:

Andrew Urquhart [Gn.?] in Miltown and Margaret McDonald alias Dow [Gn.?] were contracted 6th Novr. & married [unreadable] day of the said month

1755
Farquhar son to Andrew Urquhart [junr?] Miltown & Margt. Dow his wife born 1. & Baptd. 2d August

re the two dots: that's just a way of marking an abbreviation. We just use one these days.

The first one is yr = younger; the second one is junr = junior (the flourish at the end is a superscript r). Junior is just the Latin for younger.
