Keeping the date a secret?
According to Trump, Cruz needs to clarify his qualification. Producing his own birth certificate and then producing his mother’s birth certificate wasn’t enough. Nothing Cruz can do will ever be good enough. Trump is playing a game. Now, Trump is playing “born in the U.S.A.,” implying that natural born citizenship only passes through place of birth (via the 14th Amendment), and overthrowing all prior jurisprudence on the matter of citizenship through lineage going back to English common law.
Under British law, citizenship by lineage flows through either parent. You are confusing British law with respect to citizenship of colonials with citizenship by lineage. The latter had a expiration date, now that the UK is basically out of the colonial business.
What evidence is there that the phrase "natural born citizen" in the Article II presidential eligibility clause was inspired by and drawn from English law?
