Okay - let's start in the recent past and work backwards then:
deaths of Frank Sayer(s), 1971:
d. Frank SAYER, MarQ 1971, Sheffield RD, 2d, 292, b. 20 Feb 1919
d. Frank SAYER, MarQ 1971, Bumlingeon RD [that's what it looks like], 6b, 2902, b. 7 Jun 1887
d. Frank Alfred SAYERS, JunQ 1971, Brighton RD, 5h, 142, b. 4 Apr 1917
I suspect we're looking at the one who died in Brighton then - and the only corresponding birth record for a Frank A. Sayers in 1917 is the one in Thanet mentioned in my previous post - with mother's maiden name Williams. Given that there seems to be uncertainty about Frank's parents' names, probably worth investing in his birth certificate to confirm exactly what their names were.
deaths of Arthur (or Frank) Sayer(s) 1957:
d. Arthur G. SAYERS, MarQ 1957, Bromley RD, 5b, 214, aged 81 [1875/6]
d. Arthur SAYER, JunQ 1957, West Bromwich RD, 9b, 718, aged 70 [1886/7]
d. Frank SAYERS, JunQ 1957, Horsham RD, 5h, 535, aged 58 [1898/9]
d. Arthur A. SAYERS, SepQ 1957, Hackney RD, 5c, 593, aged 67 [1889/90]
d. Arthur H. SAYERS, SepQ 1957, Deben RD, 4b, 613, aged 57 [1899/1900]
d. Arthur E. SAYERS, DecQ 1957, Wandsworth RD, 5d, 956, aged 77 [1879/80]
d. Frank E. SAYERS, DecQ 1957, Cuckfield RD, 5h, 220, aged 68 [1888/9]
Frank E. Sayers in Cuckfield certainly matches the Tendring marriage.
