To your question on how The Dorey's arrived in Oklahoma I am not quite sure... But, this is What I do know.
Louis Dorey (Dore') born Oct. 1st 1858 Canada West - Ontario Was in Connecticut in 1877 andMarried a Marie Gingras (My Great Grandparent's) In 1886 till 1893 I show them in and around Lincoln, Nebraska Area.
1899 and 1900 I show Louis in Bristol Co. Fall River, MA. After Marie his wife past away Leaving three of his children there then returning in 1905 -
The time frames show he was either in Oklahoma between 1900 and 1905 or after 1905 till his death in 1937
This Dore Line is I can trace back through St Polycarpe, Salanges, Quebec Curran,Prescott Co. Ontario St Ours,Quebec Point - Claire, Quebec Sulpice, Quebec de Versailles, France
