Brain Stew, because anything less is uncivilized

Please excuse me if this goes a bit all over the place.  I haven’t been able to write in over a week and also have not had more than four or five hours of sleep in that period as well.  So needless to say, I am a bit out of sorts.
 
You see, towards the end of this past year, I had gotten into doing a lot of genealogy/family history.  I have been using a site called MyHeritage, and that all is going well actually.  Now, about three months ago, I decided to do a DNA sample too, for finding out more about my ancestry.  Since I was adopted, I had no hard lines back to which ever countries of origin I could be from.
 
This returned from what they tested, that I am mostly German/French, with a touch of English, Scandinavia, and Baltic states thrown in as well.  That all was pretty cool to be honest.  A few days after that though, it started to trickle in matches with other people in their database, mostly one or two percent DNA matches for far removed cousins, much like Kevin Bacon. 
 
This past Saturday though, it returned a 48.9 % match with another woman here in PA.  Looking deeper I found that she was in her 60s as well.  I thought on that for a day or two, but the following Monday, I sent in a message via the site to her.  In it I said, “Hello!  I am not out to cause any drama or anything, but I noticed our match percentage was significantly high.  I was adopted, and was wondering if you might have placed a child up for adoption in the past.”  About two hours passed and she responded back with, “Yes, I placed a boy up for adoption, his birthday was XX/XX/XXXX.”
 
My jaw hit the floor because that is my birthday.  We messaged back and forth more since then, and filled in the gaps that I was her natural son.  She always had a great regret to give me up, but had hopes that one day we would somehow meet.  Needless to say we are both a little emotional about it all as this is a significant event. 
 
She went on to tell me about her life, about the man who was my father that she was briefly with.  They never married and she hasn’t spoken with him in over forty plus years.  She went on to relate that on my father’s side, there are three older brothers and a sister out there.  She eventually met a man and moved to Indiana and had two girls.  They eventually divorced and she had a daughter with another gentleman.  They did not get married, but she and the girls made their way back to PA and she was remarried one last time, and he adopted her youngest daughter. There is an age gap of about 17 years between the last two girls.
 
She had always told her girls about me.  The oldest used to ask more, but stopped around the age of 10 or 11 when she realized how upset it would make her mother.  All of the girls have reached out to me since then, and we have all chatted a bit via text messages or email.  It’s all surreal.  A family I never knew about.  It is fun seeing who has what quirks, and tendencies, and to fill on some of the reasons why I do certain things that are unlike my parents. 
 
As I come to grips, I am sure we shall meet, my birth mother first.  After all, it’s only been how many years?  What is a few days more?!?
