Sarah Margaret Ellis

Evidence from emigration and newspaper records proves the Rees family traveled to Utah in 1859. Pioneers and Prominent Men places them in a company captained by a man named "Beebe," but there was no Beebe Company and no man by that name that we know of that traveled in 1859. He was likely a captain of ten or captain of fifty. Further research is necessary to identify the company they traveled with.

Her given name is "Margaret" on the 1859 ship manifest, 1860 Utah census and Find A Grave website.
