Thanks for the vote of confidence. This pear is one of Richard Bells creations. I don’t know a lot about it unfortunately. The pear seems like a winner Pear breeding moves toward better varieties | Good Fruit Grower. It’s certainly got the genes for thorns ‘Sunrise’ Pear in: HortScience Volume 46 Issue 1 (2011)
"Origin
The original seedling tree of ‘Sunrise’ originated from a cross of NJ5001710820 × US 446 (Fig. 1) performed in 1965 by H.J. Brooks soon after he revived the USDA pear breeding program initiated by Merton Waite in 1908 (Magness, 1937). It was tested as OHUS 66170-047 and was selected in 1977 from the seedling orchard at the Ohio Agricultural Research and Development Center in Wooster, OH by R.C. Blake and T. van der Zwet. ‘Sunrise’ is composed of Pyrus communis L. and Pyrus pyrifolia (Burm.) Nakai parentage. The sources of fire blight resistance are the P. communis cultivar Seckel and the P. pyrifolia selection New Jersey 1. Subsequently, ‘Sunrise’ has been evaluated for fruit quality, fire blight resistance, and productivity in replicated trials of clonally propagated trees at the USDA-ARS Henry A. Wallace Beltsville Agricultural Research Center in Beltsville, MD, the Ohio Agricultural Research and Development Center in Wooster, OH, and the Appalachian Fruit Research Station in Kearneysville, WV. It is currently being tested or has been tested at eight experiment stations throughout the United States for range of adaptation and productivity under a variety of environmental conditions and management systems.

I know this pear is a Barseck cross and those are typically very good pears as discussed in this post Barseck pear tree
