MyHeritage Family Tree Builder - How to connect child to their "single" parent

[SiCallear]

Hi,

Looking for some help with MyHeritage Family Tree Builder. I cannot find an answer in their FAQs, etc.

I am trying to work out how I connect a child whose father is unknown and mother is known (but widowed).

• Samuel Baker Callear was born in 1910; three years after the death of his father Percy William Callear.
• Percy's widow, Annie Elizabeth (born Baker), has two further children after the death of her husband Percy William Callear: Edith Callear and Jessie Callear.
  

I suspect it is unlikely that I find identify the father, so I need to connect the three children to just Annie Elizabeth. When I try and do this in MyHeritage Family Tree Builder, I can only choose from the list of existing parents (all couples), etc.

I am currently thinking that I may just have to add a person (name unknown)

FYI - in 1911, Annie Elizabeth is widowed and living with her brother-in-law [shown as married]

Although I don't have a tree on MyHeritage adding an unknown partner
is what I do with single mothers.
As well as making it self explanatory it may be the father will be eventually
identified.
