Looking for info on Andrew Peck (& Snyder)

[ergo]

So I collect old photos and research the people in them. I recently bought an album here in Sweden, that has a photo of "Mr and Mrs Andrew Peck". The first half of the album are photos from New York, the second half are photos from Örebro.

I'm looking to try and understand who some of these other people are in the album and would like to connect with people who know more about Peck and Snyder's histroy than is written on their website.

In looking up some family members, they're written in the Swedish census records as being "marketers" which I thought was quite unusual, but I wondered if they were perhaps business associates, or fans; possible even family. I have a couple of names, but I'm struggling to find many onlonie american archives that could help

Incidentally, is this sort of an item / story interesting to people ? OR is it just me and my nerdiness?
