HelpMeFind has two files. Le Grice (19 plants) and Legrice (83 plants). I think that the Le Grice file could be merged with Legrice, as Jack Harkness (The Makers of Heavenly Roses Pp138-144) is listing eight* of the Le Grice roses as being bred by Legrice. *Amberlight, Dusky Maiden, Ellinor Legrice, Allgold, Charming Maid, My Choice, Lilac Charm, and Victoriana.
We have separated these entries into Edward B. Le Grice (father) and Bill Le Grice (son). The cut-off year of 1977 is still rather arbitrary as the death year of E.B. Le Grice. Some roses might have to be correctly reassigned to father or son.
