How do you find siblings from your fathers side...?

Question:

How do you find siblings from your fathers side...?

if i dont know their names, or their mothers name, or thier
or ages. just know that they are way older than you, and have an idea where they were born?
if my fathers name was on the birth certificate, would i be able to find them that way? some how? how would i track down how many children he has had, if hes passed away?
nobody in my family talks about this, now and then you get to hear a roomer or two about names or locations

Best Answer - Chosen by Asker: I have been in a simular situation. First, these half siblings of yours are adults and your father is no longer in the picture. There is nothing they can take from him or expect from him.
Find the relative who might be willing to talk to you about this in private. (There is always that one relative who will talk about anything) Reasure this relative this is about adult children who can handle adult situations. Your father is no longer around to get hurt in any of this. Have passion and sincerity in your voice.
Take good notes if you do get told anything. Make 2 lists, one with possitive facts and "could be" facts. Names, dates, times, cities, states, employeers, occupations, church attended, basically anything that could tye the story together or help locate your siblings.
Once you do that, go to places like adoption. com and Cousin connect to post a search with the info you have.
Even if they are not looking, people who get board while online sometimes type in their own names to see what comes up.
(I found an aunt I did not know exsisted by typing in my grandpa's name one night. I just got board and typed in his name for the heck of it.... He had given a daughter up for adoption and she had a post that was 3 years old, still out there on the Internet!)

Again, play on those relatives who might be the keepers of secrets and play on their sympathy. (This is how I finally got the name of my birth father. My aunt finally could not hold it in any longer. I wore her guilt down to the bone, even though I was not 100% positive my father was not really my father.)

If you were to get names, look them up on the internet and a fabulous place to start is classmates.com. I have found tons of adoption-birthfamily matches from those who registered on that site.

I hope this helps some. Don't give up and be persistant!

Good Luck!!
