Alison. No marriages in Castleton in the 1800's, but I have an OPR that shows the birth of Helene, lawful daughter, born to Bryce Mitchell & Catherine Telford in Nov. 1763. This was in Govan Parish, Lanarkshire, Scotland. Don't know there's any relation. Just though I'd pass on another Telford. Judy Dawe, Saginaw, MI
