N: Thank you for your response (sorry about the duplicated 'question' - though it does emphasise the difficulties caused by duplicates). Briefly, and without mentioning names for fear of upsetting those who may end up doing the merge, I had recently adopted and completed an edit of an orphaned 2021 profile - which lacked a death date but used a "before year" birth date, nor did it show parents or siblings. A spouse was then separately created and added, as well as numerous children.The only 'source' for this 2021 profile is a link for the marriage to the spouse.
The 2021 creation is, I am sure, a duplication of the 2018 'originally profiled person', which listed dates, parents, and siblings - but not spouse nor children. Unfortunately the only 'source' for the 2018 profile is an inaccessible link to 'Ancestry'. Neither profile had been touched since its creation.
In view of the apparent duplication, apparent lack of interest by the PMs, and poor 'source' detail, I ended up scrapping my edit of the newly adopted 2021 profile and re-orphaned it.
Thus my G2G question.
I suppose I will suggest (to the 2018 creator) that a merge be completed and then offer to edit and provide relevant 'source' detail.
Thank you for your answer and your interest
