You're very welcome. If you go to the National Archives of Ireland website, and click on the link for the 1901 census returns, enter Wilson in the surname prompt, and Kate in the forename. For the DED enter Moycarky, and you will get two results, one for Kate aged 72, and one for her grand-daughter Kate, aged 9. You will be able to print off the census sheet.
Anyhow, Kate by this time is a widow, the census being taken on 31 March 1901, which suggests to me that Michael may have died in October 1900 as opposed to 1901, as it appears on the headstone. This type of error I have come across before.
Do the same for the 1911 census, but this time use Michael Wilson, and enter Moycarry for the DED....the transcriber erred in this respect. William's occupation is recorded as a "smith", so the family tradition continues.
