Josie this may help you. I hope so. Go to OGS page and find the 1861 Simcoe census page. Mush easier to work with if you actually bring up the page on McEwen on your computer. The records were prepared by the Simcoe Library.

http://www.ogs.on.ca/

Click onto the yellow box Ontario Genealogical Provincial Records Inex: This will take you top the census page.

Click onto the 1861 census which will take you to the OGSPI 1861 Census Menu and then click onto Mc under line #2 for
Algoma Renfrew "Simcoe'" then locate the page at:

Once you locate the page and bring up all the McEwen's they will be in columns in alphabetical order. Then by using the source column and the page # column you can actually put the entire families together. It appears to me that there is both a Malcolm and a Niel McEwen but your Catherine born 1848 will end up associated with Neil McEwen as her father.

If you find the page you will see what I mean.
I see the familes as such from the page: I will cut/paste the columns although you won't see them in column form.

McEwen AlexÆr. ---- 1851 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 49
MC EWEN ANNE ---- 1810 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 42 (HEAD OH HOUSEHOLD if you look at the line numbers)
McEwen Anne ---- 1842 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 46
McEwen ArchÆd. ---- 1841 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 45
***MC EWEN CATHERINE ---- 1848 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 48 (Matches her marriage dtate of birth of 1849)
McEwen Donald ---- 1845 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 47
McEwen John ---- 1837 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 43
***McEWEN NEIL ---- 1839 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 38, line 44

OK this should be the family of Catherine McEwen in 1861 in Nottawasaga.


Then you look at Malcolm MC EWEN Entirely different page of the 1861 census.

McEwen Malcolm ---- 1823 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 16
McEwen ArchÆd. ---- 1855 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 20
McEwen Catharine ---- 1857 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 21
McEwen Janet ---- 1853 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 19
McEwen John ---- 1859 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 22
McEwen Mary ---- 1860 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 23
McEwen Neil ---- 1851 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 18
McEwen Rachael ---- 1834 ---- ---- Nottawasaga 1861 Census Nottawasaga, pg 33, line 17

MALCOLM MC EWEN daughter was born ij 1857!

You will also find a third MC EWEN FAMILY listed on page 36 of the 1861 census.

How you determine who is who relationship wise is more difficult. Maybe if you call the Simcoe Libray they can send you actual copies of the 1861 census.

Neil, Malcolm and John may be BROTHERS!
