In some sources his given name is listed as "Louis."
The family does not appear on the 1856 Utah census, and the first documentation to place them in Utah is the 1860 Utah census. Family histories give dates of their arrival as 1857 and 1859, but further research is need to confirm this information.
The 1860 Utah census lists his name as "Louis," age 35. Lewis was still living at this time and none of his children in Utah had that name. It is likely that this is Lewis Brewer, born in 1804.
