There are two marriages of Rodney S Fletcher on file:

Last name  First name(s)  Year  Location
Fletcher   Rodney S       1964  London City, London
Fletcher   Rodney S       2001  Chester & Ellesmere Port, Cheshire

The temptation is to rule out the second of these (a) because it it not in the London area of his birth and (b) because he would have been 66 for his first marriage, a tad old.  However his mother’s will refers to her daughter-in-law as Nichola Fletcher and this clinches it: in the first marriage Rodney S married a Nicola J Bannister.

There are 10 Fletcher children born with a mother’s maiden name of Bannister from 1964 to 1984.

The full list of Fletcher births with a Bannister mother is:

Last name  First name(s)    Year Of Birth  Location
Fletcher   Michelle A       1964           Burnley, Lancashire
Fletcher   Thomas A         1965           Prescot, Lancashire
Fletcher   Louise Alison    1966           Tonbridge, Kent
Fletcher   Paul Edward      1966           Burnley, Lancashire
Fletcher   Kay              1966           West Bromwich, Staffordshire
Fletcher   Samantha Jayne   1967           Wolverhampton, Staffordshire
Fletcher   Timothy Wyndham  1968           Tonbridge, Kent
Fletcher   Adam Justin D    1969           Wolverhampton, Staffordshire
Fletcher   Hayley Juliet    1971           Wolverhampton, Staffordshire
Fletcher   Richard          1971           Dudley, Staffordshire

These births group into Staffordshire, Lancashire and Kent indicating three separate families, one in each area.  This impeccable reasoning gives Rodney and Nicola the two Kent children, which is certainly where Roderick’s parents lived:

Last name  First name(s)    Year Of Birth  Location
Fletcher   Louise Alison    1966           Tonbridge, Kent
Fletcher   Timothy Wyndham  1968           Tonbridge, Kent

So I have entered them up and am saving the price of two birth certificates.
