on ancestry.com i got a "close family" match, with 1,430 centimorgans shared across 58 DNA segments - it says it could be a niece, aunt, or half sibling (range includes 1st cousin, but i have read that's unlikely?) i ruled out grandparent because of age. the person attached a small family tree (only 7 people) there is a couple, gives where they were born and died, then says they had one son (name is private), then he married (shows his spouses parents, also both deceased) and that couple had one daughter. (assuming my match is the last person on tree - female) the tree stops there. only the deceased names are listed - i'm assuming the couple at the top of tree are "grandparents" of my close match (and me?)....and if they had only one son and then they only had one daughter, then she couldn't be my aunt or niece or 1st cousin...so more likely my half sibling?
i just don't know where to go because i have such limited information, no addresses, or dates of immigration, or obituaries attached, this close match hasn't logged on to ancestry in months - another possibility is the tree was never completed.
