Does any one know how can I cite M^cGarvey?

[John C. McCabe-Dansted]

In normal text I can enter a name like M^cGarvey using:
        M{\raisebox{0.8ex}{c}}Garvey
However this gives errors in a BibTeX author field. I've tried 
        M{\protect\raisebox{0.8ex}{c}}Garvey
and
        M{\protect \raisebox{0.8ex}{c}}Garvey
to no avail. Has anyone managed to cite a M^c name using LaTeX?
