A study is presented regarding the nature of several variable stars sampledduring a campaign of photometric monitoring from the Abbey Ridge Observatory: 3eclipsing binaries, 2 semiregulars, a luminous Be star, and a star of uncertainclassification. For one of the eclipsing systems, BD+66 1673, spectroscopicobservations reveal it to be an O5 V((f))n star and the probable ionizing starof the Berkeley 59/Cep OB4 complex. An analysis of spectroscopic observationsand BV photometry for Berkeley 59 members in conjunction with publishedobservations imply a cluster age of ~2 Myr, a distance of d = 883+-43 pc, and areddening of E(B-V) =1.38+-0.02. Two of the eclipsing systems are Algol-type,but one appears to be a cataclysmic variable associated with an X-ray source.ALS 10588, a B3 IVn star associated with the Cepheid SV Vul, is of uncertainclassification, although consideration is given to it being a slowly pulsatingB star. The environmental context of the variables is examined usingspectroscopic parallax, 2MASS photometry, and proper motion data, the latter toevaluate the membership of the variable B2 Iabe star HDE 229059 in Berkeley 87,an open cluster that could offer a unique opportunity to constrain empiricallythe evolutionary lineage of young massive stars. Also presented are our nullresults for observations of a sample of northern stars listed as Cepheidcandidates in the Catalogue of Newly Suspected Variables.
