Konstantin Päts was an Estonian politician. He was the first President of Estonia, from 24 April 1938 to 23 July 1940.
Konstantin’s father, Jakob Päts, was a housebuilder from Heimtali, near Viljandi. Konstantin’s mother, Olga (Tumanova), was from a mixed Estonian-Russian family and as an orphan grew up with foster parents in the Razumovsky family, where the father, her uncle, was the mayor of Valga. Konstantin was married to Wilhelma Ida Emilie “Helma” Peedi.
Konstantin’s patrilineal ancestry can be traced back to his fourth great-grandfather, Piisko Päts (c. 1685 – 10 March 1745, Holstre, Viljandi Parish, Viljandi County).
Konstantin’s paternal grandfather was Hans Päts (the son of Johhan Päts and Reet). Johhan was the son of Hans Päts and Eeva. Reet was the daughter of Hans.
Konstantin’s paternal grandmother was Mall Wirak (the daughter of Jürri Wirak and Mari Willeme). Mari was the daughter of Juhkam Särrew/Särev and Mall Satre.
Konstantin’s maternal grandfather was Hariton Tumanov.
