I found a candidate family! I had to go back and review all the families on the side of Isabella Barclay, from photo [1].
So here's how I did it...
I had already identified and placed two named and dated photos (oh, so helpful!) of two HOGG children, George Hogg and Thomas Barclay Hogg born in 1888 and 1893 respectively.
The only critique of myself that I can offer is that I hadn't placed the photos in my own family tree, but another large tree on Ancestry that I use as a reference for the Berwickshire area. So each time I scanned my own tree for a good fit family to suit the above photo, I didn't find one...
So I fixed that glitch for myself now
I've included the photos of the Hogg children here.
The parents of these two boys were William Hogg and Elizabeth Mary Barclay. The father of Elizabeth Mary Barclay was Thomas Barclay b.1813; he was the younger brother of Isabella Barclay from photo [1]. Thomas was married to Isabella Patterson b.1824.
Elizabeth Mary Barclay was born in 1862. She had three older brothers - Thomas Barclay b.1856, George Patterson Barclay b.1858 and Joseph Edgley Barclay b.1860.
So how does that fit? If the photo is for example dated at 1866 then the family would be
Man 53
Woman 42
Boy 10
Boy 8
Boy 6
Girl 4
