I hear you Chempat! But I was a little surprised that Trish had managed to pull out a list of names that looked like my ancestors (which I don't particularly mind, BTW) when I have supplied none to date on this site - my assumption being, that perhaps she knows me from another website.
So, my research centres around my 3rd GGM, Susan Smith (British Subj born France) circa 1827 and her daughter, Jane Smith Gordon (my 2nd GGM) born Aberdeen circa 1849. I say circa as the ages have varied a little across records over the decades. Regards Jane, after 1851 she's well documented and some of the info I have incl. photos have been passed down to me. However, to date I have never found a birth record for Jane. She obviously took her mother's maiden surname as her middle name, a common practice. She married Capt Wm Murray Oudney.
Her mother, Susan Smith - to date, no birth record found (France?). Susan, before marrying Wm Gordon was previously married to a John Kelly, Glasgow way, and they had a son, John Kelly, who is listed in the 1851 census as 5 yrs old. Eventually, he took on William Gordon's surname and thereafter was recorded as John Gordon. Jane is just 1 yr old on same census. I have a likely marriage record between Susan and Wm - 1851. This would indicate Jane was born out of wedlock with her parents, or Wm was not her biological father but he took her in. This is a brick wall I've had for a while.
I DNA match to a descendant in the line of Jane's brother's (Wm Gordon born 12 years later) and also to her Uncle, Susan's brother Alexander b 1824 - a DNA match to his descendants.
The only clue I have to Susan Smith's mother is from the marriage record of Alexander, her brother (born 2-3 yrs earlier) for 1883. She is listed as Jean Smith, maiden surname, Rose (but could be Rosen, or Roser) and deceased. Perhaps she was French. Can't find a death record for her, perhaps she died giving birth or didn't die in scotland. All these questions and more! Anecdotally, other family members has suggested Jane might have been illegitimate - but no proof either way.
Hope that helps.
