In 1662 an Act of Settlement was passed to define which parish had responsibility for a poor person. A child's birthplace was its place of settlement, unless of course its mother had a settlement certificate from somewhere else stating that the unborn child was included on the certificate.
However from the age of 7 upwards the child could have been apprenticed and gained a settlement for itself. Also, the child could have obtained a settlement for itself by service by the time it was 16.
