This chap, a Peruke Maker, died in 1804 and left a will:

He names a neice, Elizabeth Cook, and a natural son, Robert Dod Cook, son of Mary Chirlish.
There is a Clandestine Marriage on FMP in 1754 between Dod Cook, peruke maker, and Ann Jane Dinyon:

His burial is also on FMP.
I'm trying to find out as much as I can about him, purely as there is a Cook - Dod marriage in OH's tree in 1802.
