About us
I-M223 Y-DNA Haplogroup Project is for males that have tested Family Finder or a Y-DNA test and are predicted M223+ or are on one of the two sub-branches, I-FT355006 and I-P222 or are on one of the confirmed sub-haplogroups. Female members are welcome. I-M223 is also known as I2-M223 or I2a1b1 by ISOGG as of 29th June 2018 and was previously known as I2a2a and before that as I2b1 and I1c. We encourage our male members to test their Y-DNA and if possible to upgrade to Big Y-700. Sub-haplogroups include but are not limited to: I-A427, I-B293, I-BY138, I-BY18, I-CTS10057, I-CTS11871, I-CTS2392, I-CTS1858, I-CTS1977, I-CTS616, I-CTS6433, I-CTS7618, I-CTS8584, I-FGC15071, I-FT108839, I-FT355006, I-L1193, I-L1194, I-L1195, I-L1198, I-L1201, I-L1226, I-L1227, I-L1228, I-L1229, I-L1230, I-L126, I-L1272, I-L1290, I-L137, I-L369, I-L1425, I-L623, I-L699, I-L700, I-L701, I-L702, I-L703, I-L704, I-L801, I-L812, I-M284, I-P195, I-P222, I-P53, I-P78, I-P95, I-PF6894, I-PF6896, I-S17707, I-S18331, I-S20743, I-S20905, I-S21760, I-S2361, I-S2364, I-S24, I-S6480, I-S7753, I-SK1258, I-Y10626, I-Y10660, I-Y10668, I-Y11858, I-Y15292, I-Y36144, I-Y3670, I-Y3709, I-Y4142, I-Y4725, I-Y4750, I-Y4751, I-Y4752, I-Y4955, I-Y5282, I-Y6060, I-Y6098, I-Y7240, I-Y10626, I-Z161, I-Z165, I-Z166, I-Z170, I-Z171, I-Z180, I-Z183, I-Z185, I-Z190, I-Z2054, I-Z78, I-Z79, I-ZS3, I-ZS1.
