These photos were purchased at an antique store or flea market in the Perth/Smiths Falls area. A quick look at the records on familysearch.org shows that Ethel Patterson was living in Smiths Falls in 1951, when she registered her own birth. Frankie's birth record shows his given name was actually Francis.
