I have her on GGGF's BC - Robert ALLAN 05/07/1870 in Ayr. He was illegitimate so no husband but her mother is the witness - Jane ALLAN. On GGGF's DC, she is noted as having later married a Robert Bruce - 10/09/1889 also Ayr and her parents are noted as William ALLAN (deceased) and Jane Allan nee SMITH. No sign of natural son (Robert Allan - my GGGF) with her on any census following his birth.
Think I now go off on the wrong track. I thought I had her on 1901 census with step-children in New Ardrossan and then her DC 07/07/1924 in New Ardrossan but the parents don't match at all - Thomas and Agnes Allan nee Templeton. The witness is her eldest step-son (matches that 1901 cencus hit) so he might have got the details wrong but they seem too wrong to me. I think this might be a different Agnes Allan - not impossible that 2 Agnes Allans and Robert Bruces got married in Ayrshire - I did only get one hit on SP though.
I am trying to find her birth and have been going with William and Jane as her parents but am not having much success. She will have been born c1853 and I reckon probably somewhere in Ayrshire. I also cannot find a marriage for William Allan and Jane Smith.
I am very much hoping someone can help. This line is a nightmare to follow!
Many thanks
