Need help identifying a relic I inherited a relic that says S. Margar. vid, has wax seal and thread intact and above seal a number and date 1949 written.  I have been told this is St. Margaret of Scotland, do you agree and what does the vid mean, thank you, Kevin
Vid means widow. Reference. The date 1949 is probably when the relic was last verified and sealed.

St Margaret may well be St Margaret of Scotland. But there are a number of other candidates &mdash; Wikipedia lists the following, and there may well be more:

Saint Margaret the Virgin of Antioch (died 304) [unlikely, since widow is stated!]
Saint Margaret of Scotland (c. 1045–1093) [widowed]
Saint Margaret of England (died 1192) [never married; a nun]
Saint Margaret of Hungary (1242–1271) [never married; a nun]
Saint Margaret of Cortona (1247–1297) [never married]
Saint Margaret the Barefooted (1325–1395) [widowed]
Saint Rita of Cascia (1381–1457) [widowed]
Saint Margaret Clitherow (1556–1586) [married but not widowed]
Saint Margaret Ward (died 1588) [no marriage recorded]
Saint Marguerite Marie Alacoque (1647–1690) [never married; a nun]
Saint Teresa Margaret of the Sacred Heart (1747–1770) [never married; a nun]

You don't say what the relic is, but St Margaret of Scotland is certainly the best-known widow of that name. If the seal is identifiable, then there may be records available (for which the date and serial number will be useful).
