I have tried some of the genealogy and ancestry websites to try and build my family tree but have encountered considerable limitations due to the foreign status of most of the families.
Let me clarify. My immediate family I (mom, dad, sister, kids, wife) are pretty well known to me, no problem there, but when you start going down the parents' side of the family or my wife's side of the family things get quickly impossible. My parents even have a hard time identifying, properly ordering and categorizing the members of their family, they are in their late sixties and the family were all over the old country, so its a mess to say the least. My wife, she was young when she left hope and knows parents and brother but anything further as to grandparents, uncles, aunts and so on, is a mystery to her, most of them she has never met.
My mother's side goes back to 16 century central Iran, and my dad's side of the family goes back to 13 century southwest Iran and northwest Iran. My wife's family goes back to Hong Kong but further back to mainland China, Canton region probably and oldest daughter's mother's goes back in the midwest to southeast (such as Carolina's, Indiana, Florida, Georgia and Tennessee).
So my question is how to go about finding resources to help build this family tree before its too late, most of them are dead already but I am hoping somehow to use and supplement the ones who are alive to getting to the root of the rest and build a relatively accurate family tree, feels like time is fading.
