I recently received a "DNA Match" on my account to some one who shows 1,177 cM shared. I am trying to understand what this is really telling me.
This is important to me as I do not know who my Father is but suspect I have a whole set of half siblings from his side.
I know who my mother was and have met my 1/2 siblings from her marriage to their Father, hence knowing my niece as stated below.
I have another post that shows 810 cM shared and that individual is my niece by my half sister.
