One Record Will Help You Find...

When searching for an ancestor not already on your family tree, start with the most recent event and
work backwards-

1. Death
2. Marriage
3. Birth

When finding a birth record, it will be easier to look for a Christening record first. It sounds odd I know; nevertheless, the christening record will often include a birth date on it. Churches have a more standardized process of recording new borns so it will be easier to find. 

In addition to christening records, you may want to look for midwife journals and family bibles- these may be online, a relative may have it, or it may be at a Family History Library.
