Over the last two months I have had the interesting experience of 'internet' meeting distant relatives in Tasmania, Australia, and England, because we all a common ancestor, Mary Connor-Polkey (Harrison). The profile I have created for her is Connor-3055, which you will need to read to get the full 'jist' for my G2G question.
Mary Connor, was deported/exiled from Ireland to the women's penal colony in Tasmania, Australia for stealing in 1848-49. There she met and married James Polkey, who had lived through the same deportation/exile from his native England, for the same reason, about a decade earlier. John and Mary (Connor) Polkey had a good marriage, and eight children.
Roughly 20 years after their marriage, husband John was having serious life and legal problems... troubles that could have led to his arrest and imprisonment. With his previous exile/convict history, it is very understandable that he would not go through that again if he could avoid it.
Which he did by disappearing with Mary and three of their teenage daughters. The five of them went into hiding, took on the last name alias of Harrison, and moved to New Zealand.
The other living children, now adults, stayed in Tasmania, and kept their natural/original name of Polkey, their descendants are Polkey's.
The three teen daughters who take on the alias of Harrison in New Zealand... never in their lifetimes disclosed to their own children or any other family/relatives that they were really Polkey's. They married as Harrison's... and every one of their New Zealand civil, public, and public records is under the Harrison alias... or their husband's name. The Harrison-alias, became the MATERNAL generational family tree name of their descendants (decades & generations). John and Mary were maternal-side Grandpa/Grandma Harrison to the children of these three married daughters (born Polkey).
Research by a professional genealogist is 2020, and DNA confirmation... has revealed to the Harrison descendants that their x4 Grandmother/Aunt/Relatives (the three daughters/sisters) were actually Polkey's and that their generational genealogy family name of Harrison is an alias.
Quite a shock after generations/decades. One of the questions that they/we must address, is what name to use in their family tree now. They ARE generationally, Harrison descendants. Do the Harrison's have to change their name to Polkey in their family genealogy tree? How do you address the issue of some of the children in this same unique generation keeping the Polkey name, and some of them using the alias of Harrison in a family genealogy tree? Do they/we put the names of their ancestors in as Polkey-Harrison? Polkey-Alias Harrison? Something else?
For generations, the Australian/New Zealanders have been Harrison descendants on their maternal side; suddenly in 2020 they discover Harrison is an alias and Polkey is their real family name... how do they/we address this new 'name' information in our family genealogy tree? I would appreciate some opinions/thoughts from G2G.
