Mary Emeline Frederickson 1848-1930 Photos for dating please

[jettejjane]

I found the full length pic on ebay and by pure chance the other 2, all from separate sellers and named.  My task is now to research this lady. She  is Mary Emmeline Frederickson born 1848 (Nicholson) died 1930. Any ideas of dates please.

Hi Jane...I think the top one is 1860s and the bottom one early 1870s. Lovely photos.

(1st post)This one is early - mid 1870s as it looks to have square corners. It's always a good idea to post a scan of the backs to Jane including the corners.

Thanks Carol.  All of these backs have square corners.  I assume corners give  indication of age of picture.    I have another from my latest batch of cartes de visites, named and  dated 1877 that has rounded corners. Another named and dated 1870 also has rounded corners.  But the last named and dated 1871 has square corners.  Now I am confused

The rounded corners first appeared in the very early 1870s to enable the cartes to fit more easily into the album sleeves. Some photographers would have been using up old card stock so the dates are an estimate.
Have you found Family for her?
