We present the results of an unbiased search for Ly{\alpha} emission fromcontinuum-selected 6 < z < 8 galaxies. Our dataset consists of 160 orbits ofG102 slitless grism spectroscopy obtained with the Hubble Space Telescope (HST)Wide Field Camera 3 as part of the Faint Infrared Grism Survey (FIGS; PI:Malhotra), which obtains deep slitless spectra of all sources in four fields,and was designed to minimize contamination in observations ofpreviously-identified high-redshift galaxy candidates. The FIGS data canpotentially spectroscopically confirm the redshifts of galaxies, and asLy{\alpha} emission is resonantly scattered by neutral gas, FIGS can alsoconstrain the ionization state of the intergalactic medium (IGM) during theepoch of reionization. These data have sufficient depth to detect Ly{\alpha}emission in this epoch, as Tilvi et al. (2016) have published the FIGSdetection of previously known (Finkelstein et al. 2013) Ly{\alpha} emission atz = 7.51. The FIGS data use five separate roll-angles of HST to mitigate thecontamination by nearby galaxies. We created a method that accounts for andremoves the contamination from surrounding galaxies, and also removes anydispersed continuum light from each individual spectrum (Pirzkal et al. 2017).We searched for significant (> 4{\sigma}) emission lines using two differentautomated detection methods, free of any visual inspection biases. Applyingthese methods on photometrically-selected high-redshift candidates between 6 <z < 8 we find two emission lines, one previously published by Tilvi et al.(2016), and a new line at 1.028{\mu}m. We identify this lines as Ly{\alpha} atz = 7.452 +/- 0.003. This newly spectroscopically confirmed galaxy has thehighest Ly{\alpha} rest-frame equivalent width (EW Ly{\alpha}) yet published atz > 7 (140.3 +/- 19.0{\AA}).
