Born ‎18 Apr 1839 Canada
Michael and Mary have a "Catherine." However, in the 1861 Wakefield census of Canada, there's another Catherine Rooney living with them, listed as a servant, age 21 (b. 1840). This is probably Michael's brother Patrick Rooney's Catherine (possibly born in 1838 instead of 1840 - or splitting the two, since only their ages are listed, born in 1839 if the census months differ). Adjacent to this Catherine in the census is "Theodore Grovent" (my best guess at the spelling), age 21 (b. ~ 1837). He cannot be found under any of several permutations of the names Gavotte or Grovent in any of the censuses from 1871 1891 for all of Ottawa county.
