Yes, those are some of their children. I have a pretty good hold on their children and many of their children's descendants. I have the family at 1022 Bouck by the 1880s (the street changes name to Lafayette in the 1890s.) The son retained the house for a few decades despite putting it up for sale in 1896. Several of the children were still living at the family home in this period, and several others within a few block radius. I have not yet fixed date of death so the window I offered is a presumption on my part. If my window is correct, however, it appears all children at this time were in Buffalo. At least two children wound up residing on the Canadian side of Niagara Falls but that wasn't until a decade or two later. One of the daughters died there while visiting her brother but her body was transferred back to the states.
