I have this information provided by an advanced collector from Swedenicon as to who M. Bjorlin is to keep this post up to date for future information to all those viewing it -

"Per Mattias Björlin was born 24th of February 1894 in Stockholm. Married 1919 with Karin Dagmar von Schéele. They got together 4 boys (Claes-Henrik 1921, Per-Gösta 1923, Mats 1924 and Ulf 1933).
Per Mattias (with nickname Mats) became second-liutenant at Royal Svea Artillery regiment in 1917. Lieutenant 1922, captain 1932 and finally major 1942.
Mats Björlin was also a rather good painter, especially portraits. He is represented at the National museum in Stockholm and you can search for him here http://emp-web-22.zetcom.ch/eMuseumP...search&lang=sv He died 1986 in Stockholm."

Per Mattias granddaughter Naida (Ulfs daughter) became an American singer and actress. Read more here Nadia Bjorlin - Wikipedia, the free encyclopedia. Nadia-Bjorlin.com The Official Website
