London Parish Records since 1538 now online

"Now you can research family records going right back to the reign of Henry VIII. Our amazing new London Parish Records collection gives you a unique opportunity to see records going back further than 1837 - which is when formal birth, marriage and death certificates were introduced. Anglican churches have kept records of all baptisms, marriages and deaths in the parishes since 1538. Although some of the earliest records haven't survived, those from the 17th century onwards are in remarkably good order. You'll find the baptism records really helpful in your research, because they date back to before it became law to record a birth. So even without a birth certificate, if you discover when a child was baptised you can find out the parents names and where they lived. With these names you can start tracing their parents and the generations before them. By following the paper trail back over the centuries, you might be amazed to discover whole new London branches of your family tree.
