He was in 1840 Grayson County, Virginia, Census
2 males under 5
1 male 5 to 9
1 male 30 to 39
1 female 20 to 29
1 female 70 to 79 (Agatha Brewer his mother) as Lewis Brewer said in his will that
Rufus and Mastin was to provide her a place to live.

I did not find Rufus in any census for 1850 but I found him in 1860 Rock Island County, Illinois. He must of been in Indiana, as some of his children said they were born in Indiana.

In 1860 Rock Island County Illinois, Census;
Rufus Brewer 50 Blacksmith and farmer born Virginia
Roxanna 42 wife born Virginia
James Lewis 18 son born Virginia
Armilda 16 daughter born Indiana
Aaron 14 son born Indiana
Mary Jane 12 daughter born Indiana
Nancy Elizabeth 10 daughter born Indiana
Letty 5 daughter born Illinois
(possibly a nickname as I never found her name in the probate to sell the land I found Rachel L. G.)
