2.  Patrick Dunn (Tentative), b: 1831, Ireland. I cannot say with any certainty that Patrick is the son of Dennis. There are simularities to James though. For instance there was a Patrick Dunn born 1831 in Ireland and baptized on 27 Mar 1831 in the Parish of Mountmellick and Clonaghdoo and Diocese of Kildare and Leighlin that may be Patrick (same place as James), however, that Patrick's father was listed as Thatron - a transcription error? Also, Patrick ended up in Sioux City as did James.
     Patrick married Catherine Murphy in New York. I was not able to find either one of them in the 1870 New York Census. Their family was listed in the 1880, 1900 and 1910 Concord, Woodbury Co., Iowa Census records. Patrick died on 15 Sep 1913, leaving a Will dated 31 Jul 1913, probated 14 Oct 1913.

     c. Elizabeth Angus "LIzzie" Dunn, b: 11 Feb 1880, Woodbury Co., IA. She married William Daniel Parks on 20 Nov 1900, Sioux City, Woodbury Co., IA.

     f. Infant daughter, b: unknown, d: stillborn

     From the Sioux City, Woodbury County, Iowa Families by Marjorie Bennett McArthur:   Patrick Dunn was born in Ireland about 1831; the area is still questionable – Cork, Kilkenny or Wexford. He came to the United States about 1861 and remained in the New York area. He married Catharine Murphy about 1872 in Mamaroneck, Westchester County, New York. Two children were born in New York; John about 1874 was stillborn; and Margaret Ann ‘Maggie’, 23 May 1878.
     When Margaret was only a few months old, the family moved to Woodbury County, Sioux City, Iowa, on a farm north and east of Leeds. It was difficult to make a living as there were few settlers in the area and many Indians living along the Floyd River in caves and tents. They would often come to the Dunn farm seeking food –milk, eggs, bread. Grasshoppers destroyed the crops several years in succession. Elizabeth Agnus ‘Lizzie’ was born 11 February 1880. Mary Alice ‘Mollie’ was born 16 October 1881. Another daughter died in infancy.
     On 22 November 1881 they moved to their new home a mile and a half straight east of Leeds – Concord Township. There were eighty acres on which they had an apple orchard and raised various fruits, livestock and grains. Patrick raised his own tobacco ‘down near the barn’. All the girls went to the country school a mile away from their home and then went to Sioux City. They attended St Joseph’s Catholic School, while working for their board and room. ‘Mollie’ especially was so happy when Friday evening came so she could go home to the farm to help ‘Pa’ with the chores and field work.
     Patrick was very fond of his own daughters and all his grandchildren. His favorite expression upon greeting their buggies as they arrived was ‘By the Law, By the Law’. Catharine treated the youngsters with her fruits and jellies stored in their basement. Patrick wrote many letters and cards to his daughters and families – always keeping in close touch. Fire destroyed their home, claiming most everything they owned. Having rebuilt, Patrick continued to farm until shortly before his death, 15 September 1913.
     Patrick had a brother, James and a sister, Mary, who also came to the United States. James came to Sioux City in 1869 to homestead land, gaining title thereof 20 August 1875. Mary made her home in Connecticut.
     Catharine Murphy came to the United States as a little girl about three years old. Her ‘Aunt Eliza’ raised her and a sister, Mary, who died at age 18. She lived in New York assisting her Aunt and Uncle in their haberdashery. She was asphyxiated from gas fumes in her home in Leeds, 29 December 1917.

3.  Mary Dunn (Tentative) , b: unknown, possibly Ireland. She went to Connecticut.
