Neighborhood where Williams family lived in Dowlais, Merthyr Tydfil, Wales. [No Longer Considered a Match]

Our DNA - R1b1b2 Haplogroup

The following are the known Y-markers for the DNA of the William Williams of Llanddewi Brefi line:


Irish tradition suggests that the Celtic people originated from a union of a Scythian and an Egyptian princess who took over Northern Spain before going on to conquer the British Isles. DNA similarities in recent years show strong similarities between the genetics of the Celts and Basques, who largely reside in Northern Spain. So not surprisingly, it looks like we are of the R1b1b2 haplogroup.

It is said that the Basques have primarily the O blood type and have the largest percentage of RH- of any other people by far at 33%. Again not so surprisingly, my blood type is O-.

David Thomas Williams (1850); First Williams to America

David Thomas Williams (b. Nov/Dec 1850, d. 9 Jul 1927) was likely born to Edward and Harriet Williams in Dowlais, Glamorganshire, Wales. David married a Mary Jenkins (b. c1856/57 in Dowlais), probably on 2 December 1873 in Dowlais. David worked as an iron puddler and lived with his family behind the Bear Inn in Dowlais in 1881. David and Mary had the following children while in Dowlais:

David John, b. 22 Feb 1874

Edward, b. 18 Sep 1875, d. 7 Feb 1924
William, b. Feb 1878, d. 4 May 1918 
Evan Leo, b. 18 Sep 1880, d. 16 Dec 1954

Sometime between the spring of 1881 and summer of 1882, David and his family moved to Stockton, Durham, England. While in Stockton. Mary gave birth to:

Harriett, b. 13 Apr 1883, d. 26 Sep 1927

In late June 1882, David left alone from Liverpool, England aboard the SS Parthia and arrived in New York on 6 Jul 1882, while the rest of his family remained behind in England for another three years, probably when he raised enough money for them to make the journey.        Mary Williams arrived in New York from Liverpool, England via Queenstown, Ireland aboard the SS Wyoming on 11 Aug 1885, with her children David, Edward, William, Evan and Harriett.

Given that son Ivor was born in Pennsylvania, by at least 1886 the family was living in the South Side of Pittsburgh in the town of Birmingham.

David and his family remained in the South Side of Pittsburgh through the remainder of his life. In 1900, David and his family were listed at 77 South 16^th Street in Ward 28. David was working as a “leity laborer.” As of 1906, the family was living at No. 2 South Diamond St, where David's wife Mary died at the age of 48 on 30 November. She was buried in the South  Side Cemetery. Her death certificate says that her father's name was David Jenkins.

After coming to the United States, David and Mary had the following additional children:

Ivor, b. 16 Mar 1886, d. 16 Mar 1943
Margaret, b. 30 Aug 1887/89, d. 18 Feb 1932
Thomas, b. 28 Jun 1892, d. Feb 1955

Map of area were family resided from c1886 to c1908.

They lived in the neighborhood through at least the 1920s.

By 1912, David had moved in with his daughter Margaret Gerwig and family at 1415 Bingham St. In 1914, he was again living with his son Evan at 94 S. Fifteenth St. In 1915, there was a David and David J.  at 2113 Sarah St, both listed as laborers. In 1916 and 1917, 

In the 1920 census, David was listed as living with his children David J., Harriett, Thomas, and Ivor at 1211 Bingham St. David was listed as working at the steel works. That said he was crossed out on the census record as a duplicate. His son Ivor was duplicated, but he was not. It said that he arrived in America in 1886 and was naturalized in 1892. In 1921, the directory listed a David, Harrriett and Ivor still at 1211 Bingham St. Another David was listed at 1307 Bingham St.

David died in his late 70s at 4:30 am on 9 Jul 1927 of senility and gangrene of both feet. The doctor had been treating him for about 2 1/2 months. At the time of his death he was living at 40 S. 20th St in Pittsburgh with his son Ivor, who was the informant of his death. David was laid to rest at the South Side Cemetery on 12 Jul 1927. Unfortunately his parents were listed as unknown on his death certificate.
