I too am looking for Maynards - but pre 1820 & Rolvenden-Tenterden part of Kent (other side of Tunbridge Wells than Speldhurst). From 1881 LDS census Edward Maynard aged 68 widower was born (1812/13) Speldhurst living with his daughters Elizabeth 38 U (1842/43) & Emily 34 U (1846/47) at St Pauls Estate no 15, Speldhurst.
Henry (b1843/44) living with wife Eliza (b1842/43). I guess you have most of this, but missing from your list are the other siblings of Harry (b1846/47 Speldhurst) namely: Mary J.(1869/70); Emma (1877/78) - note that the ages are more or less correct from the census but as it was always taken ca. 2-6 April - the LDS dates of birth are often 1 yr too high.
I guess you have tried the LDS site for data, what about freeBMD.com ?
Good luck with your research & stay in touch should any links in our Maynards appear, regards Jeremy.
