Go raibh maith agat
Thank you.
The everyday thank-you: to one person; the plural form changes the ending.
The wording is quoted exactly from the record and its cited source; personalisation touches only your own names and date, never the Irish.
About this saying
Irish has no ancient single word for thanks; what it has is better, a blessing. Saying thank you in Irish is literally wishing that good may be at the person, subjunctive and all, which makes every small courtesy a miniature benediction.
