Another Old Photo

Another family photo..probably taken in 1902 or 1903.
Left to right is my great grandmother holding her son. Her husband is by her sitting on the ground. (he is my great uncle) Next to her is my great gr. aunt holding my grandmother's sister. Then the man sitting on the chair is my great grandfather.My great grandmother was married to brothers.  Her first husband (my uncle) and son (on her lap) died the same year. I don't know how or why.  Then later, she married his older brother, who is my grandfather.  They had a daughter--my grandmother.  Incidentally, my great grandfather - Alfred- in this photo is the same one I'm picture with several posts below. My great grandmother died, too, when my grandmother was a young child, in 1911. Again, I don't know how.  She died the same year and month as the Triangle Shirtwaist Factory Fire in NYC..where she resided. I don't think there is any connection, I just find it interesting to be able to put a timeline to it, as I watched the PBS show about the fire just recently.
