It is frustrating that none of the censuses for the time period in question seem to be available. And I can't find a death for Jean Pierre Mederic Malhomme or Marie Louise Marchand. I did find Virgine on the riencourt census living alone 1872 I think it was. I couldn't read the occupation. My Poor French again. I couldn't make out the letters.
I was going to look through the census in Abbeville and Le havre ( Louis Malhomme married Ellen Aline in 1877 & shed been in Le Havre the year before.) But that's a lot of pages so will take me some time. But if they were in Amiens or Riencourt, I won't be able to find them.
Thank you though for your offer of help. I'm sure i'll be back asking questions before too long.
