Census records:

Robert married Mary Ann Selwood in Shelby County, Indiana, December 17, 1840. His name is listed in the record as as "Richard Sidgewick."

They lived in Shelby County, Indiana 1850. They moved in 1859 to Crooked Creek, Cumberland County, Illinois, where they took up a farm of 80 acres, but they were apparently in Illinois as early as 1853 or 1854, because in the 1860 census and the 1870 census they listed the birthplaces of Matthew and Margaret as Illinois. In August of 1851 Robert sold two tracts of land in Shelby County, indiana (see the conveyence records below); this may indicate the time of the move to Illinois.

Robert died in 1874. Mary appears in the 1880 census. James still lived nearby. Mary died in 1900. They are buried in Washington Cemetery in Clark County. (There appears to be a Washington Cemetery in Cumberland County and one in Clark County; I understand they are at the one near Casey.)

Children:

Effa Jane married a Mr Mullen, had a son James Howard Mullen (b. abt 1868 Indiana) and died young. Howard was raised by Effa's brother his uncle William Sedgwick.

William, the middle child, never married, but stayed on the farm and looked after the family. He cared for his mother in her old age and raised three nephews and a niece, William "Ardy" Groves, son of Jonathan and Sarah, Effa Jane's son James Howard (called Howard) Mullen, Margret Ann's son John England Sharp, and Mary Olive's daughter, Rosie Hardin. What a saint he must have been! William bought his siblings' share of the farm. He died June 24, 1934 and is buried at Cumberland County, Illinois, Washington Cemetery (There are two Washington Cemeteries, one in Clark County, one in Cumberland.)
William appears also in these census records:

Margaret Ann (b. July 14, 1854, Indiana, d. September 8. 1879, buried Casey, Clark Illinois, Washington Cemetery) married August 10, 1878 at Cumberland County, Illinois (at bride's home) John England Sharp (b. 1832 West Halton, Lincolnshire, England, d. December 2, 1886, buried Casey, Clark Illinois, Washington Cemetery). John was an immigrant ancestor, son of John Sharp (b. 1805 West Halton, Lincolnshire, England, d. England) and Jane England (b. July 14, 1805, Whitton, Lincolnshire, England, d. 1840 England). Margaret and John had a son

Mary Olive Sedgwick, b. August 10, 1864, Crooked Creek, Cumberland, Illinois, died March 10, 1887. She married December 24, 1885 at Clark County, Illinois, Thomas J Hardin (Ancestry.com database Illinois Marriage Records, 1851-1900)

A family sketch appeared in a publication, "Cumberland County History." John Warren had it on his website, but the website has disappeared and I have lost touch with John.

Robert Sedgwick Family

Robert Sedgwick (born 9 May 1809, died 23 May 1874), son of John and Ann Sedgwick, and his wife Mary Ann Selwood (born 12 November 1819, died 25 October 1900), daughter of Henry and Nancy Selwood, came to Illinois from Indiana with their family in the late 1850's. They entered 80 acres of land in 1859 in Crooked Creek Twp. They were the parents of 12 children:James R., Sarah Elizabeth, Effa Jane, Robert, Thomas Henry, William, Gideon, Margret Ann, Mathew, John Wesley, Albert F. (died young), and Mary Olive Sedgwick. Robert Jr., Mathew,Sarah and her husband, Rev. Jonathan Groves, moved to Texas in the latter part of the 1800's.

William Sedgwick, the middle child, never married, but looked after the family when his father died in 1874. William's sisters had all married and died, leaving children. William Groves, Effa Jane's son, James Howard (called Howard) Mullen; Margret Ann's son, John England Sharp; and Mary Olive's daughter, Rosie Hardin. William also cared for his mother in her later years, until her death in 1900.

William Sedgwick was a farmer and hay buyer. He operated the farm his father had entered in 1859. He also made some money during the oil boom of the early 1900's. During his final illness, he was cared for by his nephew, John England Sharp, and John's wife, Daisy D. Snyder. Because of this, John and Daisy inherited the Sedgwick farm from William when he died in 1934 (William had bought out the other heirs prior to his death). William Sedgwick's death certificate, filed by John E. Sharp, stated his cause of death as a carbuncle on the neck.

Robert Sedgwick and Mary Ann Selwood are buried in Washington Cemetery, as is William Sedgwick.

Cumberland County History.

Mary had an uncle named Solomon Henry, who was born in Pennsylvania, lived in Shelby County, Indiana, then moved to Putnam County, Indiana, where he died. He had no spouse or children and no surviving siblings. His estate was divided amongst his surviving nieces/nephews. Mary A. Sedgwick received her share of Solomon Henry's estate in 1898. She had executed a power of attorney to W. Dale Sedgwick who received the funds in her behalf.

The above information was provided by Kath. Sullivan <sully@vnet.net>, who provided the following transcriptions of two documents pertaining to the receipt of this inheritance, vis:
