Mama Bear & two cubs

The dogs were going wild at the window, rare since they are used to deer, turkey, and chipmunks walking through the yard. I looked out the window to see two little bear cubs just 8 ft away on the front porch.  It took awhile for my brain to register what I was seeing; two large cats? No, what then?  Oh!  BEAR CUBS!  Mama was there also.  I grabbed the camera but evidently did not look at the screen, as I only got Mama in the picture.  I heard that there is a Mama with three cubs.  I wonder if this was her or if this is another family.  My hands were shaking - the pics are poor.
