Well there you go. I'm not sure I can work it out as far as your own generation is concerned but Elizabeth Oliver (Paramore/Barratt) was my grandmother. As far as we know she was full sister to Harry Barratt and half sister to Clara, Annie, Rose, Fanny and Joseph Barratt and she was I believe half sister to Mary Ann, George, William and John Paramore. Now that is not entirely certain as there is some confusion over birth and death dates for her and her "father" Henry Paramore. If you have more information I would be keen to hear it.
