Allan ,
Many thanks for looking up a marriage for me, at first it looked promising as on the 1870 census they are living in Illinois. However I have several census and Jane is listed as Jane C on all of them . But you set me thinking , I have 1870 census ,1900 , 1910 , 1930 ,but no 1880 or 1890. thats a gap of 20 years . So I set to and really studied the census`s and on the 1900 I found a column which stated how may years they were married . 30 yrs. I have just twigged the significance of the numbers , just always looked at the names . That info is going to be very handy ! I then looked on Ancestry for a marriage 1870 and found one for St Joseph , Indiana .I think that is a suburb of Elkart ,Indiana ,which is where John`s sister lived . It lists John G Stevenson and Jane C, Surname . Unfortunately I don`t have Ancestry Worldwide . But I feel I have moved a step further forward . Sometimes you just need a push in the right direction .
Much obliged to you
Evelyn .
