I believe this is a thing in Quebec.

In Quebec, the Civil Code requires parents to assign their child only one surname (either a single or compound surname) derived from their respective surnames. Compound surnames may not have more than two parts, with or without hyphens. Thus, a couple named Joseph BOUCHARD-TREMBLAY and Marie DION-ROY could give their children the surnames:
- BOUCHARD
- TREMBLAY
- DION
- ROY
- BOUCHARD-TREMBLAY
- DION-ROY
- BOUCHARD-DION
- BOUCHARD-ROY, and so on.
In Quebec, the law provides that spouses retain their respective birth names when they are married.
I saw some documentary that suggested that they used to chip straight through fossilized feathers and skin to get to the bones because they didn't realise what they were.
