Someone PLEASE help me find out who this lovely woman is!

Of all the pictures I acquired the other day of handsome gentlemen; precious little babies; and pretty ladies in the most splendid of dresses, this is the one picture that spoke most to me.

This picture was taken in 1890 at G. & W. Morgan, located on 5 Market St. in Aberdeen, Scotland. Presumably (because of the location the photograph was taken), she is a Scottish girl. She looks young, maybe in her late teens, so perhaps she was born in  the 1870s? The negative number of this specific picture is 16635. She has a sister and two brothers; I know this because I found the following picture, which I also bought:

Quite the nice family, wouldn't you say? Anyways, the back of her photograph had nothing written on it except the print that came with the card, saying the name of the photography company as well as the negative number, as seen below (it's rather difficult to see because I've sealed the pictures in air-tight bags):

As for the back of the family photo, there is a bit of writing by the son of the boy with his arms crossed in the photo. He wrote: "Chap with arms folded is my Dad George Fordyce. His Brother Andrew + 2 sisters." ...the writing is quite messy and I'm unfamiliar with Scottish surnames, so I don't know what exactly to make of it all. Regardless, I'm assuming that the family photo consist of children all with the last name Fordyce. What annoys me is that the two aunts of the person writing on the back of the photo stay nameless! The father's name is mentioned, the uncle's name is mentioned, but what about the two women?

I've been trying so hard to find out any information about these people on Google, but nothing has come up. I can't even find a website of all the pictures taken at G. & W. Morgan to sort through them myself in order to find what I'm looking for. If anyone can decipher the writing on the backs of these cards better than I have or know who are in these pictures, please let me know! I would be so, so, so thankful!


UPDATE: The Aberdeen library emailed me back regarding information they found about this family. Click here to go to a link where a picture of the directory where G. & W. Morgan is listed. Hopefully there will be more updates to follow! :)
