It's known that Lyapunov brothers were descendants of a family of Konstantin Yaroslavich [ru] of Galich and one of his sons, dukes of the Duchy of Galich and Mersk [ru][note 1] both of whom itself belonged to Rurik Dynasty.[2][3] Their ancestors ruled in the Principality of Galich (an appanage of the Vladimir-Suzdal Duchy), until Duke Dmitry Donskoy, Grand Duke (Prince) of Moscow annexed their domain in 1362 and exiled Prince Dmitry Ivanovich of Galich, who fled to Veliky Novgorod where he entered the service to the local archbishop. Around this time Lyapunov family has lost their Duke title (the exact date is unknown though) and were considered boyars of the Novgorodian archbishop.
Their sons, the great-grandsons of Prince Vladimir Dmitrievich, namely, Dmitry Beryoza (meaning birch), Semyon Osina (meaning aspen) and Ivan Iva (meaning willow), were the progenitors of the Beryozin, Osinin, Ivin and Ilyin noble families.
Lyapunov's family ascends to a boyarin (servant) of Pimen "Black" [ru] (1571, an Archbishop of Novgorod and supporter of Ivan IV) named Ivan BorisovichLyapun' Osypin (Russian: Иван Борисович Ляпунь Осипин), from which Lypunov (Russian: Ляпунов) family name has started.[3] Lypynovs acquired a dvoryanin title when one of Lyapun' Osypin's grandson entered servitude of Duchy of Ryazan (dissolved around 1521) and joined the Ryazan nobility.[2][3]
The grandson of Semyon Osina, Lyapun Osinin, is considered the founder of the Lyapunov family.
Ssavich Petr Lyapunov (Russian: Ссавич Пётр Ляпунов, often referred as Лепунов, died 1587)[5] according to Razriady records served in different cities: as Head of Cheboskary (1583),[6][7] Dankov (1584, next to a Muravsky Trail);[8] he had a wife named Denisova-Ushakova Nikiforovna Anna (Fetiniya - before marriage).
