I wonder if it may be a way to ask you about the importance of where we come from, making sure you are aware of this for your own family history. So you can be aware that your new little child or baby may also want to know about their history and/or be able to integrate into your life and your family story.
I think an awareness of how this is/may be very important to some might be useful.
As an example from our own family... we are a close knit (not large) family, our son is an integral part of it. But we know he has another family, his birth family.
DS is not currently very interested in his birth family and is very keen on granddad and grandma.
We have done a number of things to prepare for the the time when he may be more interested, tried to keep in touch with birth family (through letterbox), kept photos, kept all the things that he came with (toys/cloths etc) that may be of interest.
I guess being aware of where we come from and how knowing things affects us might be useful in terms of understanding your new little one's history, preserving some of that for her/him and also integrating the new member into the wider family. (This is all guess work.)
