If she really was born around 1216, which by the way are an estimation,
Cecilie Oxlev and had 7 children, of whom we do not know the order, then it would probably had taken her at least 10 years to complete it. It's assumed that she had her first child at the age of 14, the last child would be born around 1240 if she had them in a row, but if that's true or not, we don't know, they could all as well have been born between 1240-1250...
When doing any estimation, we do need to have some sort of fixed time point, hints that make a guess more likely, without it we just stare in blindness out in the dark, and at that point, the minimum demand would still be that it's chronological possible. It doesn't matter if the names are X or Y, it only has to be credible.
Before I added the line to Ingerd Jacobsdatter Hvide first husband Conrad Graf von Regenstein, II and his date of death, 1246, nobody who had not the done research for him could have know after which year she married her second man, and as long as nobody knew, 1230 could have due as their sons date of birth, thus, there we have it. Anyway, as I wrote before, if he really were a son of that pair is not proven.
Lastly, it's not wise to lock down any profile that's unfinished or only partly completed. Please, unlock it.
