The ancestry of both my maternal grandparents was a mystery for many years, but thanks to DNA and advice on this forum (
https://www.rootschat.com/forum/index.php?topic=664349.0), I was able to solve my grandfather's life and parents. But my grandmother still has me stumped, and I'm wondering if I can get any general advice please.
My gran was born in Melbourne, Australia in 1891 and the only record that matches her shows her mother was an unmarried 19 year old girl who gave her name as Mary McDonald from Ballarat (a nearby regional city). No father was named. She was named Olive Blanche, and subsequently adopted by Charlotte and John Clark. (There were no adoption records at the time, so this is all probable but not certain.)
The situation is more complicated by the fact that Charlotte Clark was subsequently accused of allowing another adopted child to die by neglect in a practice known as "baby farming" - a woman agreeing to raise an orphan child in return for money then neglecting the child to save money. In a much publicised court case, all those involved in that unfortunate adoption (mother, hospital and Charlotte) gave false names, so it is quite uncertain if the mother was really named Mary McDonald.
I have taken DNA tests with FTDNA and Ancestry and transferred results to My Heritage and Gedmatch. I have also had my mtDNA tested with FTDNA.
I have contacted and examined many atDNA match records, identifying which are maternal and paternal, etc, but so far nothing stands out. I have tried tracing the lines of a few of the best matches to see if anyone ends up in Victoria, Australia at the right time and so far haven't found anything obvious. The mtDNA shows all the latest matches are from Ireland (or Finland before that) and one distant atDNA and mtDNA match was from Ireland, so it seems likely that my Gran's biological mother was from Ireland - there were many Irish immigrants to Australia around that time.
I feel at a loss what to do next. I am not expecting anyone here to be able to solve the problem, but I'd really appreciate some advice, please, on the best way to proceed. Should I ....
.... spend the time to try to trace every decent match forward to see if any end up in Victoria?
.... do a lot of work on match surnames and locations to see if anything stands out?
.... just keep waiting to see if a good match turns up?
.... find some fancy DNA analysis that shows which matches are most likely (is that possible?)?
.... employ someone to do some advanced searching?
I have time to do the work if only I could decide on a productive course. All thoughts welcome thanks.
