. . . unless it was done many decades ago - if which Im not sure you will be able to get a copy of any certificate. But the date of it occuring should be on church membership records.
Hello @Julee Hicks. I would think this is something the ward Clerk would just print out and get signed. As far as I know, The certificate received after a childs blessing, would just need re-writing or printing. Hope you can get it oganised 😊.
