Working on my Clark, Le Clear, Campeau & Amo lineages

I was up pretty late researching – working on my Clark lineages – got abt 90% already done – just filling in the blanks – I am also working on my Le Clear, Campeau & Amo lines – mostly settling in Detroit, MI from Canada – I believe the Clark lineage to be Native American – 3x Grandmother Lucretia Le Clear (then from her daughter Maryette Emaline Clark (married into the Barkhamsted Lighthouse line William Barber), Ada Barber, Alvin Allen, Rex Allen – Me) Lucretia was noted Mulatto (also a reference to being Native American) in the 1850 census in Rollin, Lenawee, MI age 6 yrs. In the 1900 census Owosso, Shiawassee, MI age 57 she is listed as white she also lists her birthday as May 1843~
