Our earliest record, so far, of Lyda LaBrune is the 1895 Iowa state census, where she is the 13 year old daughter of Jean-Baptiste and Catherine LaBrune. It was just recently that a conversation with some of Lyda's great-granddaughters provided a clue to discover her pre-adoption family history.
Lyda was one of three daughters born to Oscar Arnold and Emma Olive Goodwin. Oscar and Emma were married in Cascade, Dubuque county, Iowa in 1879. Verda, Lyda and Bessie were likely born in East Cadcade, in 1880, 1882 and 1883, respectively. There was also a son born in 1886, but I have no record of his name. Oscar was a "laborer" and the family was together through 1885, according to the censuses. But Lyda filed for divorce in 1887, claiming "inhuman treatment" and "desertion". The court filing was reported in a western Iowa newspaper where I believe Emma was living, possibly with her mother, Elizabeth Goodwin, and brother, David. We don't have much information on what happened to the family in the next few years. I found no more records for Oscar, Bessie or the son. In about 1894, Emma married Lars Peterson, a 32 year old Swedish immigrant, working for the railroad. They had four children: Ada (not sure because she was born about 1891), Herbert (1895-1975), Florence (b. 1897, married Lester Care), Pauline (b. 1899) and Elmer (b. 1902), all born in Iowa. By 1910, the Petersons had moved to San Diego, where Lars worked in a lumber yard. They apparently went with more family: Emma's mother and brother, Eliza and David Goodwin, moved to Los Angeles, while Emma's sister, Ida Tibbets, moved with her family to Long Beach.
We know that Lyda had joined the LaBrune family by 1895. I've found no further records for Bessie and their brother. In 1895, Verda is the 13 year old daughter (was actually 15) of Lewis and Liddie Board, farmers in Cascade, Dubuque co., Iowa. Arly, Ray, Emma and Lyle, ages 0 to 7, are their other four children. In 1902, Verda married Bill Gearhart. In 1908, Bill died from what I assume was a head injury received in a baseball game. The newspaper reports that he was a well known member of the baseball profession, playing for the Cascade Baseball Club. (See Bill's FindAGrave record for an obituary and photo.) During their brief marriage, Vera and Bill had six children: Glenn (1903), Curtis (1904), Lee (1906), Vera (1907, later married Turner) and Ila (1908, later married Scolaro). In 1911, Verda married Daniel Moore, described in censuses as a house painter and a custodian. They lived in Cedar Rapids, where their son, Elwood, was born in 1912. Elwood died in 1934, 22 years old. I have no information on the cause. Daniel passed away in Cedar Rapids in 1956, Verda in 1962.
I have not been able to find any information on Lyda's father, Oscar Arnold, outside of the six years of marriage to Emma from 1879 to 1885. Census records say that he is from Pennsylvania or New York, and that his parents are also from New York.
Emma Olive Goodwin was born in 1860 in Dubuque county, Iowa, the oldest of five children born to Thomas Jefferson Goodwin (b. 1832 in Indiana) and Eliza Summers (b. 1841 in Iowa). Emma's four other siblings were: Alonzo (b. 1862), Ida (b. 1865 in Montana), Rolie (1876-1877) and David (b. 1878). The family was mostly raised in Cascade, though they must have been in Montana in 1865, when Ida was born. Thomas was a "road master" (charged with maintaining a length of road?) and a laborer. He passed away in 1882 and is buried in Cascade. I've found no more information about Alonzo. In 1883 Ida married Pedermar Jester, a barber. They had seven children before Pedermar passed away in the late 1890s: Willie (1885), Mary (b. 1886, later married Robert Aikens), an unknown son (b. 1888, died before 1895), Irene (b. 1889), Garnett (b. 1892, d. late 1890s), Albert (1895-1959) and Neva (b. 1897). In 1905, Ida married Stanley Tibbets. By 1920, they had divorced. Ida passed away in Los Angeles in 1945. Rolie died in Cascade when just ten years old. David Monroe Goodwin stayed with his mother, from Cascade to western Iowa, to Los Angeles. When he registered for the draft in 1918, he was living near his sister, Emma, in San Diego, and gave her as a contact, so I suspect that their mother, Elizabeth, had passed away before then. In the 1930s and '40s he was living in San Luis Obispo county. He passed away in Ventura county, just north of LA, in 1952.
