Hi I hope this is the correct forum to ask about Ancestry ThruLines DNA if not very sorry but please point me in the right direction

I have a DNA showing my 3 x Gt Grandmother’s mother my 4xGt Grandmother

Is this a reliable source ?

If so my 4 x Gt Gran is on BCC twice

If this is not a reliable source of information- it’s back to the drawing board

Thank you
