Okay, I spent a few minutes at the HS checking on obits. There was nothing for the Brittinghams. There ia a very brief announcement of the death of Rachel, and an obit for Harvey H. I was going to copy them, but the HS was closing - I can go back if you want them. I also checked the index to Erie RR applications, which the HS has in its collection - found nothing for Harvey, but most of the applications date from the early 1900's. Have you found the Erie RR website? There are several Eggleston entries there. Try this link. http://freepages.genealogy.rootsweb.ancestry.com/~sponholz/a...
I also took a look at the index to Mt. Pleasant Cem. in Union Twp. - which is not "in" Meadville, but miles out in the countryside. It was considered unkempt and somewhat derelict in 1975, and it may be worse now. Apparently there were lots of broken stones, also.
I noted that there were lots of Egglestons in northern Crawford Co., near the border with Erie Co.
Sorry I didn't find more. I will check at the court house the next time I am there.
