I have KASK in my family tree. Karl KASK.
On 16 September 1914, my great grandmother, Margot HOLM married Karl KASK. My grandfather, Harald HANSBERG was almost 4 years old at the time. His father, Ernst HANSBERG, had passed away on 7 January 1912, of pneumonia.
Karl KASK was born 8 March , 1881 at Arensburg (Kuressaare), and died of heart disease on 10 July 1926 at Tallinn, Estonia. I do not know, but assume that Margot and Karl were married in Estonia.
If you think there is a link between my KASK and those in your family tree, you may email me if you would like.
Thank you,
Lisa Hansberg McMillan
