Trying to identify early 1920s family car

[Seamooretx 0]

My grandmother and dad early to mid 1920s picture.  My brother and I wanted to identify the car and find pictures of a restored version.

Thanks for any information or suggestions on how to identify.

Looks like a 1927 Pontiac Landau Sedan.  Hub caps, running board apron, sun visor bracket, door handles, landau bar, rad cap, body moldings and bumper match.
