How can i know that who was the ancestor of my family?

Answer 1

start with your parents, use birth, death and baptism records. They list their parents. If you have older living relatives they can give you dates. It is a long trail to get to the end if you ever do. Records back in the 1700-1800's aren't the greatest if they even exist. That's the easiest way to find out. Please understand that genealogy is an expensive and fun hobby. You can find free documentation at cemeteries and obits if you have dates.
Happy hunting!!!!

Answer 2

Hey Shine,

Given the definition below, your Grandparents are Ancestors, and their parents, etc.
--------------------------------------------------------------------
an·ces·tor (ăn'sĕs'tər) pronunciation
n.

1. A person from whom one is descended, especially if more remote than a grandparent; a forebear.
2. A forerunner or predecessor.
3. Law. The person from whom an estate has been inherited.
4. Biology. The actual or hypothetical organism or stock from which later kinds evolved.
----------------------------------------------------
So, you start with your Birth Record, and see your parents names, birth dates and locations. Get their Birth Certificates and will find the Grandparents names, birth dates and locations. Same for the Grandparents and succeeding generations. You can use Genealogy software to track this if you plan to do your family tree to go way back, to determine your ancestors say for example 12 Generations out (or even further).

Here are some software packages that only cost about $30.00 and some charts if you don't want to go that far.

If you do decide to do the Family Tree come on back for some more assistance, there are no less than about 20 great people here willing to help.
