Just a thought - Did notice a John Moore born 1874 Antrim. Ireland - Wife Lizzie also in Clackamas - wouldn't happen to be a brother of Thomas would it ? Children were Thomas, Ina, John, Norman, Willard, Hector James, Angus and Arabell ? They immigrated through Canada and then border crossing St Albans - August 1905. Going to Oregon City. Oregon.

Quite possibly you may only be interested in the Lamont angle though
