Merge deceased Mom’s iPhone Photos into my iPhone Photos
My Mom passed. She had an iPhone 8 (v16.7.11) with 1,200+ photos & videos, dating back to 2014, which I have whittled down to 781. I have ALL her credentials. I have her iPhone.
I have an Apple One Premium subscription with Family Sharing and she is a family member. Though I know that her photos are saved in my 2TB of storage, I don't want to keep her iPhone 8, and I don't want to have to log into her iCloud.com account to see her photos. I want to 'merge' all of her Photos into my Photos, maintaining the Date Created order, eg. photos that she took in 2016 actually appear in my 2016 order of photos, not all clustered into an 'imported' 2025 clump of photos.
I consider myself fairly technically savvy (not as savvy as my kids), but I do like to follow specific instructions. As long as the instruction steps appear on the screens I'm looking at, they don't have to be verbatim.
Can this be done with just my Apple products, or do I have to "buy an app" for that (which I'm willing to do).
Thank you in advance, for your condolences and your guidance.
