Miranda McGregor

[chempat]

Maidie and Noel Yeo Robertson may have got married in 1927, as old friends, but they have a son who dies in the war (in 1943 age 21 - Warrant Officer J F P Robertson). 
They are 'of Johannesburg, Transvaal' at the time.

Added:
Just looked on Ancestry trees, a goldmine of conflicting information for them and marriages, births and deaths all over.

Mary Elizabeth Pim /Madie Doris Pim married Mr Dodd in Aberdare in 1900, she was an actress, he was a producer/agent.
Divorce reported in July 1913 - she was living with Mr McGregor in Liverpool because she had been in the panto there (1912-1913 season I assume) , and had had a child, who was definitely MacGregor's.  That would fit with the first birthdate in 1939 of 13/12/1912 for possible daughter Miranda.  Though difficult rehearsing for a panto if heavily pregnant as a Principal BOY?? They had met in Glasgow when she was doing panto and he worked there. (1911-1912?)
As Maidie was Irish, performed in Glasgow where she met Mr McGregor in about 1911, and toured throughout UK but in Liverpool as stated, birth could have been anywhere, and under Pim, MacGregor, McGregor, Dodd, Scott surname.  Don't think birth was as Miranda.

She might not have been the mother of Miranda, could be totally a false trail, as trees do not seem to know about a child - child could have been given away.

Have applied for a will and one marriage certificate, so far.

I can’t find the 1900 marriage which must have happened as they divorced!

Births of twins
 1922 John F Macgregor mmn Pim Pancras
And Mary D Macgregor

Yes.  I think the trees that have Miranda think she is Mary D, as Mary was born in 1922.  2+2=5

She would be 10 yrs old if she is the one who marries Ernest White

I don’t know anything about Miranda McGregor, but I have Mary Elizabeth Pim in my tree as she married my relative John Francis MacGregor. (He is my 1st cousin 3x removed - born in Glasgow).

Here’s a summary of what I have on her:

1881: Born Mary Elizabeth Pim in Maryboro, Ireland
1900: Married Alfred James Scott Dodd, in Merthyr Tydfil
1913: Divorce proceedings begun (final decree 16 Feb 1914) - based on her adultery with J F MacGregor
1914: Married John Francis MacGregor, in Marylebone
1922: Twins born on 23 Nov - John Francis Pim MacGregor and Mary Diana MacGregor
1925: Divorce proceedings begun between the MacGregors. Wife’s petition.
1927: Marriage to Noel Yeo Robertson

Date unknown: Emigration to South Africa with Noel and the twin children

1943: Death of son John in WW2 (Italy)

Mary Diana (the daughter) married Richard Hugh Shapter Robinson in South Africa in the 1950s, or so I have gleaned from another tree!

Thanks avm228.
So it may be that the trees which we first looked that have Miranda in them have associated her with the wrong family 
However, the divorce proceedings mention a child which would be earlier than the twins.
Hopefully the marriage certificate will help.
