According to Wikipedia AG Findlay took over the business Laurie and Whittle (London geographical and print publisher) on the death of Richard Holland Laurie in 1858.
I do not know if RH Laurie is the Laurie of Imray Laurie Norie and Wilson Ltd but given that in about 1820 Laurie published a chart showing Cape Belsham AG Findlay and Imray, Laurie etc etc seems to be a promising line of investigation.
