Are they Heins or Meyer?

The caption in The Meyer Book reads Mrs. Heinrich Heins and Heinrich Heins each caption under their own pictures.
I had forgotten all about an error with a picture in the Meyer book. This picture is from page 140. The opposite page has a description of Maria Dorothea Heins's life. The man in the photo could be her brother. When I took that trip to Iowa four years back, I was reminded that a Heinz caption was in error. But was it this Heinz picture or another picture.

Does anyone else know, if it is true?
