Notes:

When I searched the actual 1881 Census of Gwinear on the film, it indicates Mary Jane is "deaf and dumb from fever". The identical census, which can be accessed on the internet, omits this information.

History of Richard Hendra and Mary Rowe AND Richard Williams and Emily Jane Thomas
as told by Bernice H. Williams 7 May 1978
Richard Williams and Emily Jane Thomas were married in England. They had one son, Harold before Richard came to America. Six years later, Emily followed with Harold. They lived at 634 N. 5th Street, Ishpeming, Michigan. They had 6 more children before Richard died.
Richard Hendra was a boarder at the Williams home. Mary Rowe was the maid. They married and had 2 children, Arthur and Myrtle. Mary got homesick, so Richard brought her back to England along with the 2 children. She died while there. Richard returned with the 2 children.
Then Richard Hendra married Emily Jane Thomas Williams. They had a stillborn boy and Roy Irving Hendra.
The home at 634 N. 5th Street stayed in the family until the summer of 1973 when its only occupant, Stanley Williams died. It was then sold to a family by the name of Niemi.

Notes:

According to the index for the 1900 census, Arthur's birth is in 1892, not 1891

Arthur married Louise L. 1927. Louise was born 16 Oct 1904, Illinois; died 8 Dec 1982, California. [Group Sheet]

Notes:

Buried:
I looked (May 2009) for her grave at the Ishpeming Cemetery and it was not in the location that the cemetery record office said it was. They looked up in the original record and found someone had crossed out her name and said, "not here."
I believe she is buried there, but the records are incorrect and so we couldn't find it.
We looked again in July 2013 and found her buried in the same plot with her father, Richard Hendra

Myrtle married Williams, John Henry 12 Jul 1920, Detroit, Wayne, Michigan. John (son of Williams, Henry and Martin, Margaret Jane) was born 25 May 1884, Beacon, Camborne, Cornwall, England; died 17 Jul 1963, Newberry, Luce, Michigan; was buried 18 Jul 1963, Newberry, Luce, Michigan. [Group Sheet]
