What I’ve pieced together so far.
My great grandfather’s line:
Karol Gawrys is as far back as it goes. Karol Gawrys (might have different spelling in Poland) was born (likely) in 1844 and married Kornela Kamiska (no other information). I believe they both died in Poland. They had (most likely) eight children who were born in Lomza (for those information is available). Their children: Konstanty, Wanda, Mary, Jerzy, Karol, Leon, Edward and Josef.
My great grandfather Konstanty Gawrys (Gawryz) was born on May 11, 1884, in Lomza, Podlaskie, Poland, the son of Kornela and Karol. He married Kornella Domitr and they had ten children together. He then married Frances Wusciwujewska in 1942. He died on August 9, 1960, in Buffalo, New York, at the age of 76.
There is some information about Wanda: Wanda Gawrys was born on November 28, 1894, in Lomza, Podlaskie, Poland, the daughter of Kornela and Karol. She married Martin (Marcjan) Chrostowski on May 13, 1913, in Altus, Arkansas. She died on September 1, 1973, in Westbrook, Connecticut, at the age of 78.
Mary C. was born on September 8, 1878, in Lomza, Podlaskie, Poland.
There is a Russian language birth record for Leon for which I found an English translation:
“Birth Record of Leon Gawrys in vestry book
Posad Stawiski. It came to pass in the village (of) Poryte on the 15th (27th) of June 1891 at 1 p.m. The father of the child Karol Gawrys (47 years old) the warder of the Zemstvo living in Stawiski presented himself to report the birth of the child. The child was shown in presence of Antynego Romankevich (40 years old) and Stanislav Kharubin (52 years old), both farmers living in the village (of) Poryte.
Place and date of birth. The male child was born in posad Stawiski on the 24th of May (5th of June) of the current year at 1 p.m. The child was born by the legal wife of the one presenting himself Cornelia Kalminskyh (44 years old). On this day the christening was performed. The child was given a name Leon. The Godparents of the child were Konstantin Polotsky and Tekla Markhevka.
The entry was read by the priest Marzion Vlokshovsky and signed by the father, the witnesses could not write.”
On my great grandmother’s line:
My great grandmother Kornella Domitr and her twin brother Sigismond were born on June 24, 1884, in Kucze Male, Podlaskie, Poland, their father, Adam, was 41 and their mother, Maryanna, was 40. She married Konstanty Gawrys (Gawryz) on May 17, 1904, in Lackawanna, New York. They had ten children in 19 years. She died on September 3, 1941, in Lackawanna, New York, at the age of 57. (I looked up Kucze Male; it looks like a very small town).
Her father was Adam Domitr, born on December 24, 1842, in Orlikowo, Podlaskie, Poland, his father, Ludwik, was 36 and his mother, Rozalia, was 32. He married Maryanna Saraczewska on November 24, 1862, in Jedwabne, Podlaskie, Poland. They had nine children in 20 years. He died on July 26, 1904, in Kucze Male, Podlaskie, Poland, at the age of 61.
Adam was born to Wojciech Domitr, who was born in 1784, the son of Marianna and Maciel. He married Marianna Domitr on February 28, 1808, in Burzyn, Podlaskie, Poland. They had five children in 18 years. He had one brother.
Wojciech was born to Maciel Domitr who had two sons with Marianna Samacka between 1784 and 1789. Marianna may have died in 1789.
