↑This memorial appears to be him. The U.S. records for John vary greatly, giving a birth anywhere from 1855 to 1860, but not a single one is as early as the 1853 date on this memorial. The variability suggests there is no written family record. Likewise for his wife. So it is not clear how credible the gravestone could be. The marriage record lists Annie's parents as Patrick and Margaret Farrell. The Find A Grave memorial shows a gravestone giving her birth as 1857. Yet her birth is Mar 1862 in 1900 census, 1867 in 1910 census, 1862 in 1920 census. Find A Grave identifies her mother as {{{1}}} (Find A Grave)115872024|Margaret (Fitzpatrick) Farrell}}, 1927-3 Mar 1910. The death certificate for Margaret (Fitzpatrick) Farrell on 3 Mar 1910 gives her age as 67, so born about 1843, not 1827.
