Hello 092086
Ancestry can be very costly even more from oversea if your ancestor are from the UK and can be addictive.
Some people do their ancestry by the England and Wales census and GRO BMD's start year from 3rd quarter July -Sept 1837 (Scotland start year is different) as most dates are pritty accurate (Not all in census). Within reason of GRO certificate cost this is fairly with in the scope of most peoples interest and budget.
Those who go back further! Marriage from 1754 to pre 1837 don't give age usually giving Full age or Minor (14 to 21years old a special licence for these called 'bond marriage by allegation and did give the actual age) also they don't give the parents name. The marriages pre 1754 were single line entries in parish registers like "Joseph Blogg X Mary Doolittle got married" (Nothing else)
Baptisms pre 1837 in most cases were within a year or two of birth but could be 20 years later or more. IGI LDS index have alot of Baptisms but not all and most have to be found from Libraries/ Archives this they charge anything around £25 English pounds a hour to search for them with or
without a find. If you get a common surname name and there are 2 or3 or more baptized within a year of each other or so also christian names were very common like John, Joseph, William or Sarah -Mary-Hannah etc you can really be up the Swanee creak! Those fortunate to live near Archives can find details in Wills-Deeds-land tax-Poor law- Tithes- Allotments -Quarter session Tax rolls and many more records but from oversea its a real challenge and expensive.
This is just the tip of a very heavy large ice burger (A big Mac burger at McDonald's maybe cheaper hobby)
Have Fun though!
or go round the ruddy twist trying!
