Dear Ms. Mastrovich,
Thank you for posting your request on History Hub!
Since September 30, 1885, marriage licenses have been issued by the Clerk of Orphans Court at each county courthouse. Pennsylvania marriage and divorce certificates are available from the county courthouse where the document was issued. Please contact the Washington County Register of Wills/Clerk of Orphans’ Court to request these records.
We hope this is helpful. Best of luck with your family research!
