Etta and Carl Sanderson

We are pretty sure that this is Etta and Carl Sanderson. We think this is taken around the time he became a citizen in 1893. It was taken in Malden Mass. They had 2 sons: Carl Jr, and Harold. Carl Jr was my step Grandfather, but the only grandfather I ever knew. Carl came from Sweden and changed his name to Sanderson when he became a citizen. We're not sure what it was before.
