Ok
You opened up a can of beetles here, CG4. But that is why this forum exists.
So, on your first question.
Why so much concern about whether the Emerys had a phone?
Well, it speaks to whether Morse received a call about the murders while he was visiting family on Weybosset Street in Fall River.
Supposedly, there are conflicting newspaper accounts on what Morse said when he arrived at the Borden's on the day of the murders. One paper said that he mentioned receiving a phone call but Morse denied that such a call was ever made. It was Edwin Porter who first mentioned in the Globe that Morse received a call informing him of the murders. But from what I remember it said that he received a call but not on "who's phone", if in fact that was really true. Interesting to note that there is no talk in Porter's book about the Emerys having a phone or a call being made. Hmmm

Since Morse was at the Emery home it would be assumed that Dan Emery had a phone. Of course this speaks to conspiracy theories.
Why is it important that we know whether the Emerys had a phone??
That Morse was in on the murders and received a call to inform him that the deed was done. Conspiracy Theories and unproven that it ever happened.... and unlikely.
William Spencer, in his book
The Case Against Lizzie Borden did not speak to whether the Emerys had a phone because he could not prove it. He made calls and tried to find an early 1890s directory of the period but could not find one. Despite countless mentions here and there that Emery had a phone, he could not prove it. He even called a Telephone Museum in AZ but they could not find any listing for the Emerys. So he left that information out of his book.
I highly recommend William Spencer's book. He was one writer who stuck with the facts..... facts that he uncovered and made certain were correct. Or else it did not go into the his book.
You must remember that Telephones were an exclusive medium in the 1890s. I have seen a National Phone directory, the earliest I have ever seen, dating back to 1895 and the earliest directory on record at the telephone museum in AZ.

"National", meaning the nation's telephone grid. Fall River is listed in it. Almost every phone number in it is for a business, with the exception of a doctor or two. I don't think there was one private citizen. People did not have phones.
At the beginning of telecommunications, phones were not a necessity and very expensive. It is highly unlikely that the Emerys had a phone. Emery was a foreman at the place where he worked. A grunt. He would probably not have money or the need for a phone. Just another employee. The listings in the 1895 phone book were mostly factories, mills, and the people who owned them. As a matter of fact Doctor Bowen, who supposedly had a phone, was not listed in the 1895 directory. And just because Bowen mentions receiving a phone call does not mean he had a phone. He could have received a call via a local business. And if phones were new, directories were even newer. How did you get your name in a directory? Did you have to apply, give permission, Pay? Questions one needs to consider.
So, did Daniel Emery have a phone? I would say most definitely not. All that's out there is misinformation and grape vine rumor.
And by coincidence..... I will mention that I worked for New England Telephone, Bell Atlantic, and Verizon for over Thirty years... and that there is any specified or related relevance here may be minuscule, you understand.
And there you have it. Remember CG4. You asked for it.
