Don't think the following Lefaucheux-Laffiteau-Rieger connection has been noted, but while looking for something else stumbled up on some info:
Interesting tid-bits of info on the successors of Eugene Lefaucheux. Seems neighbour Jean Pierre Laffiteau married Constance Lefaucheux(sister of Eugene Lefaucheux) on February 7th, 1859 and acquired one leg of the firm. He files for protection for some touchmarks and then takes Henry Rieger under his wing in 1871. Not sure how Henry Rieger came into play but it is a little too early for Henry Rieger to marry into the Laffiteau family, unless he married a Lefaucheux
