The will of Henry that passed away at Walverton House Dalkey... his wife was Louisa and son was Arthur and he was a Major General in his majesty Army, I would think his line would have broken away at Henry Bingham marrying Anne Vesey or from Major Charles Bingham marrying Marie Blennerhassett both at mid 1600's and in Ireland near Dublin.... I don't think anyone in my Maj Denis line reached those dizzy military heights... I'll still pencil in Maria ... you said she was daughter to Maj Denis ... thanks another piece in the puzzle
