No evidence/sources have been to presented that prove which of her father's marriages Joanna belongs to. Based on gaps in birth dates, it is probable she is a child of the first marriage, but considering that all these marriage and birth dates from England are asserted without sources, Joanna is listed as being in both marriages to avoid the having a subsequent user create a duplicate pages for her. Please do not change this arrangement unless you have and cite high quality sources that clearly resolve this ambiguity.
