The Gilbert ORSER that married Catherine BOWERMAN was a JUNIOR on the marriage record. So the Gilbert that married Catherine BOWERMAN had a father named Gilbert.Also in the 1852C his age is 47 (born 1805),with Catherine age 43 in the 1861C his age is 57 with Catherine , in 1871C his age is 66 (born 1805)with Catherine age 61. The Gilbert son of Arthur is alive in 1852 and 1861C with Horace ORSER and per census info he was born 1793-1795. The error was simple to make with 2 Gilbets close in age, but so VERY DIFFICULT TO ELIMINATE! Gilbert the son of Arthur died Nov 1, 1873 in Kingston. Gilbert the son of Gilbert died after 1871C probably in Ontario Co., Mara 2 where I found him and Catherine on page 12 microfilm C9977. I looked in 1881C for Mara and did not find either of them.
