Why does Google show Matthew Garber as an old man? (See details)?

I was looking into "Where are they now?" type bios for the cast of Mary Poppins (1964) and for some reason Matthew Garber, the actor who played Michael amd died at age 21, is always accompanied by a photo of a much older gentleman.

If you Google the cast of Mary Poppins, this picture is shown next to Garber's name on the cast list, and if you Google the actor the same picture is shown in the bio.

But Garber was 21 when he died in 1977; so why does Google keep pairing his bio with a recent-looking photo of a 50-something year old man? Is there another notable actor also named Matthew Garber? I can't find anything about him if so.
