Hi Steven
Welcome to Rootschat.
You will get lots of help and advice for sure here but firstly you will need to post a bit more information:
Do you know when/where either of them were born/married/died? Do you have any birth/marriage death certificates with any dates/places?
Any known brothers/sisters/parents?
With some idea of dates etc., we can post some ideas of how to get the information you are after.
Look forward to your posting - post exactly what you know then we can guide you.
