The subscription site Roots Ireland has a December 6 1822 baptismal record in the Kilconduff/Swinford RC parish for an Andrew Kenny with parents John Kenny and Bridget McNicholas. There is a 15 year gap in baptismal records for the parish from July 1826-May 1841. If Andrew's age in the 1911 census (81) is fairly accurate then the record I located could be for a different Andrew Kenny since the census would indicate an 1830 year of birth. However, this record is a lead. Maybe he was closer to 88 in 1911.
There were no Winifred McManus baptismal records earlier then 1864 so likely her record was in the gap period.
Roots Ireland only shows eight children but it is possible a record was missed. What I located was Eleanor 1855 Mary 1857 Bridget 1859 Judith 1860 Patrick 1864 Thomas 1867 Honor 1870 Andrew 1874. You may want to search the Swinford parish register I would start in 1861-1863. https://registers.nli.ie/parishes/0133
FYI. House number in the two censuses had no meaning. RIC constables would go into a townland and the first house visited was House 1, the second House 2 etc. This informal numbering system usually resulted in the same house having different house numbers for the two censuses.
Let me know if you have any questions.
