I found that there are a few family trees that are incorrectly supposing that Robert Dilly born 1601 Died 1671 in Clifton, Bedfordshire;
is the first born son of Cope D'oyly (D'oyle) and Martha Quarles).
I have an extract from a book that clearly indicates that the first born some of Cope was John, and that they didnt live anywhere near Clifton.
It seems more probable that George (1567 - 1638) is the father of Robert Dilly born 1601.
Refer to attachment of the book I found on Google.
