I contacted the Harsen Island Historical society before I posted this and the head of the society drove out to the house and concurs that this is the same place.

I have an Aunt that lives on Harsens Island so this photo was of particular interest to me. After perusing the internet, I found another pic of the Morgan residence.

This image clearly shows a square or rectangular piece of land (where the flag is)in front of the house surrounded by water. This feature is quite unique, so I went on Bing Maps and found a property that still has such a unique characteristic. It is located 4-5 houses east of this mansion that's for sale. The mansion that is for sale shares obvious characteristics with the Shorpy photo, so it sure looks like the Morgan Residence, but the square/rectangular "island" makes me wonder.

And not always in the right direction. After some research of my own and contacting the St. Clair Flats and Harsen's Island Historical Society, I found that the house still stands, albeit not in quite the same form as it was intended. It's at 1250 Circuit Dr. on Harsen's Island in the Flats and is up for sale. Anyone interested at a million eight?
