Hi, first time poster here.
William shows up in England in 1891, in the household with my g-g-grandmother Sarah Jane (nee Isherwood, first/only legal marriage to a Crowther). Besides birth details on Census entries I know nothing of his pre-1891 life. Hence I'm here

1891 - recorded as born 1853 Morecambe. This location seems an aberration. Occ given is Railway Plate Layer.
1901 - born abt 1852, Scotland). Occ: Road Labourer/Highway Watchman. A tick/checkmark is visible in the final (Disability) column of the Census (viewed the image).
1911- born abt 1852 Scotland. Occ: Watch Man, for the Urban District Council. Listed as "Cripple since 1892". Nationality box shows "510" in red ink when viewing the image; this was code for "Edinburgh residents" in this Census. He clearly is not an Edinburgh resident at this point, having been with my g-g-grandmother for at least 20 years in Golborne (Wigan and Leigh, Lancashire).
William dies in late April 1915, recorded age at death 63, so possibly born 1851 I guess.
Sarah Jane dies in 1935 with her death registered under surname CROWTHER (her gravestone also reads Crowther). William and Sarah had three kids together; their oldest son Henry began using Brown-Crowther for a surname at his first son's baptism in 1914.
I have only three Y-DNA (111 markers) matches on FTDNA - almost all of these have the surname Black, and those that have gotten out of the USA in their paternal line research all seem to go back to County Antrim. I have opened contact with all of my living Y-DNA 111 matches with varying degrees of success.
That's what I have! Please and thank you for any help!
