Some web pages on this Seton fellow (apparently the Pitmedden branch of some lot of Setons, very high and mighty) say that he married Eliza Henrietta Lumsden, the daughter of Henry Lumsden of Cushnie. However, the original newpaper announcement of the wedding (I haven’t seen the original, only excerpts on the web) says John Lumsden of Cushny, relict of JP Wilson, so I believe the information in the chart.
