Both profiles have identical sources for identical data points. They should be merged; however, you just proposed the merge today, and you need to give the profile manager of Swain-287 reasonable time (up to 30 days) to approve or reject the merge. Although familysearch.org shows the surname to be Swain, the actual certified birth transcript which was the basis for their entry spells the surname as "Swaine". (Father William Swaine has the end "e" in her birth record as well, though profile is under Swain-157.) As such, Swain-287 should be merged into Swaine-427. Sometimes profile managers can be touchy about the spelling of "their" ancestors' names. The actual source for birth indicates that Swaine is correct, and is supported by the marriage record using Swaine as the spelling, also.
