Probably an Elaeagnus.

I agree; the second picture really looks like Elaeagnus umbellata, autumn olive. They are an invasive tree, all over New England, esp MA. If it is, in early fall it should have a great show of red edible berries

The berries do make a nice jelly but there are many, many native or at least non-invasive trees, shrubs, etc. that offer edible fruit but that do not take over our landscapes at the expense of our native flora. Birds eat the berries & spread them far & wide. Excerpt from http://www.metrowestdailynews.com/article/20131015/NEWS/310159887 - "Originally introduced to the U.S. from Asia in the 1830s, in 1963 the
heavy-fruiting cultivar ‘Cardinal’ was selected by the USDA as a superior,
larger-fruiting strain for soil stabilization, highway screening and wildlife
cover. Unfortunately, soon thereafter it began multiplying explosively.... Selling or transplanting Autumn Olive plants is prohibited in Massachusetts and
many other states where it is proven to be an invasive threat to native plants,
and rightfully so. "

I was in no way promoting the autumn olive, just stating fact. Do note I did mention it is invasive.

And I was merely emphasizing that fact!
