Per Vivienne's comment, please do not use MyHeritage or any other family trees as a source. If MyHeritage has reliable sources on their website, feel free to use those. However, I don't recall ever seeing a wikitree profile with a source citation to a reliable source on MyHeritage.
You may also want to you contact Anne B to see what her thoughts are. She seems to have put in the most work on the profile and is an excellent genealogist.
